The distributive property of multiplication states that multiplying two factors together gives the same result as breaking one factor up into two addends, multiplying both addends with the remaining factor, then adding both products together

For example: 480 divided by 8. You know 48 ÷ 8 = 6

Then 480 have a zero that zero you should add it to the answer 6 now you have 60 and you finish.

A variable is a letter or a symbol that stand for a number or numbers example: j+5

An expression is NOT an equation because it doesn’t have an equal sign. There’s 2 types of expressions: Numerical (ex. 2+4) and Algebratic (ex. 4x-3)

Find the numbers that you are going to use and find the clue words like purchase and gave that means subtract and words like more mean add.

Kim has a $10 bill, a $20 bill and 2 $5 gift certificates. She uses both the $5 certificates to pay a $14 CD. How much money does she have left to pay?

To add a decimal you need to add normally and align the decimal point.

To add a decimal you need to add normally.

You only have to multiply by how many is the exponent or power and multiply it

Sandi is 13 years old.Dennise is 3 times Sandi´s age.How old is Dennise

And now, what do you have learn of Numeration with this lessons? THE END!!!

Lesson 2-2 Rounding whole numbers and decimals

Whenever you want to round a decimal check the tenths place, if the digit in the tenths place is 5 or above round your whole number up, if your digit in the tenths place is 4 or below then your whole number stays the same.

There are four&nbsp;properties involving&nbsp;multiplication that will help make problems easier to solve. They are the commutative, associative,identity propertie and zero&nbsp;propertie.

That any number you multiply by 1 equals the same number

You can change the group of the factors but the product will stay the same

You can change the order of the factors but the product stays the same

The zero property is that any number multiply by zero is zero

Step 1. forget about the decimals Step 2 round to compatible numbers Step 3 divide

Estimation: Decimals Divided by Whole Numbers

If you want solve a Multiple Step Problem here is an example

Step 1. Multiply as with whole numbers. Step 2. Count the total decimal places in both factors. Step 3. Sience there is a total of place in the factors, there is 1 decimal place in the product.

Lesson 2-4 Draw a picture and write an equation

To find the equation and the picture you need to draw you need to find clue words like Tommy has 5 apples and gave 3 to Timmy.

A community center is raising funds to buy a computer. The community center has raised $1000 of 1600$. How much more money does the community center need to raise?

A quotient is the answer to a division as the drawing shows 11 R8 is the quotient.

Numbers have a lot of place values and they are ordered from great  to least

The ones are the first numbers in a number there can only be 3 places for the ones, the tens, and the hundreds

The ones can only have until the 9 it can only have 1 digit, the tens 99 they can only have 2 digits, and the hundreds until 999 they can only have 3 digits.

The thousandths places are after the ones and they have a comma between them

The thousands can only have 4 digits, the ten thousands can only have 5 digits, and the hundred thousand can only have 6 digits.

The millionths places are after the thousandths places , they also have a comma between them

Every place value that is greater will add 1 digit.

Lesson 2:Comparing and ordering whole numbers

Lesson 4: Comparing and ordering decimals

If you want to solve a problem like 2,700 divided by 300 you have to cross a zero for a zero but if you have 2,700 divided by 3 you underline all the numbers that aren’t zeros and then divide normally does two numbers like example 27 from the 2,700 and divide 27 by three then you add the two zeros from 2,700 to the quotient and finally you already solve the problem.

There are several ways to estimate quotients. example: There are 216 students. The school has 8 classroms. How many students will be in each classroom? Estimate 216 ÷ 8

You can round to estimate a quotient. You can also use compatible numbers to estimate a quotient. And you can also use multiplication to estimate a quotient.

The place value is super important on the digits. The ones place: this is the first place you can only put numbers from 0-9. The tens place: is the second place you can only put numbers from 10-99. The hundreds place: in this place you can put numbers from 100-999 this is the third place from the place value. And like that is going the place value.

I will give an example of a Pattern: Each day Maria reads 5 pages of his book on Monday he had 5 then on Tuesday 10 on Wednesday 15 and on Thursday and Friday how much does Maria will read. Answer: Thursday 20 and on Friday 25.

Step 1. Align the decimal point Step 2. forget about it and divide normally

A pattern is a series or sequence that repeats

Step 1. understand the problem step 2. solve

Problem Solving: Multiple-Step Problems

To subtract decimals you need to subtract normally and allign the decimal point.

&#160;Step 1. Align the decimal point Step 2. Move the decimal point right as many times as in the divisor there is no decimal point and in the dividend the times you made to the right to the dividend to Step 3. Divide

Lesson 2: Comparing and Ordering Whole Numbers

To compare a whole number you need to see the numbers in both whole numbers so the bigger part points to the bigger number and the little part point to the other number Ex 1543&gt;1322

If both numbers are the same you use the equal sign 1254=1254

Making and investigating mathematical conjectures. Developing arguments and proofs. Students who reason and think analytically tend to note patterns, structure, or regularities in both real-world and mathematical situations

The order of operation is PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, and Substration.

you only need to multiply one digit by one digit

to multiply 2 digit by 2 digit then you multiply each number 

you multiply the same because you apply 3-4 and 3-5

When you compare numbers you need to think which number is greater, you need to compare like which is greater 1,437 ? 1,246, and here is a trick first see at the thousands place, there are the same, hundreds 4 is greater than 2, so 1,437 &gt; 1,246.

5-8 Missing or extra information

If there’s missing information you do not have the information needed in a problem If there’s extra information you do not use all the things written on the problem

The extra information is the number of red balloons that didn’t blow up

Divisions are the opposite to a multiplication.

One digit quotients are answers to divisions such as this one:

If you want to solve a division with multiples of 10 here is an example

We hope you liked our book and that you learn something.

First step: look at the numbers, then move the decimal point 1 time to the right; then Multiply.

Multiplying Decimals by 10, 100, or 1,000

By: Mauricio Garza Díaz, and Eduardo Bernal Villarreal 

First step look at your numbers. Second step round&#160; Third step solve

Estimating the product of a decimal and a whole number

The order of the addends does not affect the sum.

Addends may be grouped differently, but the sum is still the same.

The sum of any number and zero is the same number.

Lesson 2: Estimating Quotients with 2-Digit Divisors

If you want to estimate a problem like 566 divided by 81 you first round to the nearest compatible number the you cross out a zero for a zero and divide normally.

Lesson 2-3 Estimating sums and differences

Whenever you want to round a decimal check the tenths place, if the digit in the tenths place is 5 or above round your whole number up, if your digit in the tenths place is 4 or below then your whole number stays the same. Knowing this information you will only need to add or subtract the whole number.

lesson 5-7 Estimating and dividing with greater numbers.

First step look at te numbers then move the decimal point 1 time to the left then cross out a zero and divide.

Dividing Decimals by 10, 100, or 1,000

Step 1. Multiply as with &#160;whole numbers&#160; Step 2. Count &#160;the total number in decimal places in both factors

using mental math is like 4 ✖️5 = 20 so 40 ✖️5 =200 and 400✖️5= 2000 and even 4000 ✖️50 =20,000
