    Adding fractions is a way to find the total amount when you have two or more parts. To add fractions, you need to make sure that the denominators (bottom numbers) are the same. If they are not the same, you can find a common denominator by multiplying the numerators and denominators by the same number. Adding fractions is an important part of mathematics, and it is used in many different ways to find totals and solve problems

    We use the number 10 for counting things. Imagine each finger represents one number, like 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. When we run out of fingers to represent a number, we add another set of 10 fingers and start counting all over again. This system of counting is called the decimal system.

    Multiplying decimals is just like multiplying whole numbers, but with an extra step at the end: You can do it like this: 1) Line up the decimal points. 2) Multiply the numbers. 3) Put the decimal point in the answer. If you have a total of two decimal places, we put the decimal point in the answer directly over two spaces from the right.
