Step 1: How to Add Whole Numbers

This is the most basic of the basics. All you need to do is keep counting up. For example, 7+3=10. To learn the concept, you would count up to seven, and then keep counting up three more numbers. Ex, 1,2,3,4,5,6,7 (then the next 3) 8,9,10. There are three more numbers added on to the original seven and that is basically how it works. Obviously, you cant do this when adding big numbers, but there is a better way for that. Line up the numbers vertically and, starting at the right, add together the numbers that line up. Look at the pictures (coming soon) for more detail. If there is a number 10 or greater, place the units value, left, below the line and carry the ten's digit number up and to the left. Next time you just do the same and add on the remainder from last time. If you have any questions or if I have mislabeled or spelled something wrong please leave a comment. Thank You.

2. 3+(-5) (ignore the parenthesis, They just mean it is plus negative 5)
3. -6+(-2)
4. -2+1
5. 5+(-3)

Step 3: How to Add Fractions

Adding Fractions is once again a basic concept, but occasionally it can get hard. Once you have mastered basic addition-adding up to 12 and 12-and multiplying-up to 12 and 12-you can do this. If you have a basic fraction where the denominators (the bottom part of the fraction) are equal, such as 1/2 + 1/2, you can just add the top numbers and keep the bottom the same. The reason for this is if you have half of a pizza, and your friend has half a pizza, and you put them together what do you get. A whole pizza. if the denominators are not the same, you may need to cross multiply. If you have 1/2 + 1/3 you multiply opposites. 1 x 3 and put it in the upper left. 1 x 2 and put that in the upper right. And multiply the bottoms and that becomes the denominator of both fractions. Now you can add them normally. In order to simplify fractions, you must know how to divide. Divide the numerator (top) and the denominator (bottom) by the same number. This works because 1/1, 2/2, 3/3, and even 99/99 all equal 1. If you divide by one, the number remains the same even though it appears different. If you have any questions or if I have mislabeled or spelled something wrong please leave a comment. Thank You.
