they both have something to do with positive and negative
Addition and subtraction are inverse functions.

Addition, subtraction and multiplication.
They are different in the same way that subtraction of integers is different from their addition.
You are likely to get a different answer.
Subtraction of integers is essentially addition of integers except the second integer is inverted. For example: 5 + 3 = 8 is a simple addition of integers. 5 - 3 = 5 is a simple subtraction of integers. It can be expressed by inverting the second value (the one right after the subration sign) and then switching the subtraction sign to an addition sign. So it would look like: 5 + (-3) = 5. Note that (-3) is the opposite of 3. So to do a more confusing subtraction problem like: 55 - (-5), we could rewrite this as: 55 + -(-5). From here it's easy to see that the two negatives cancel out. 55 + 5 = 60.
The rules for addition are as follows:The sum of two negative integers is a negative integerThe sum of two positive integers is a positive integerThe rules for subtraction are as follows:If they are two positive numbers, do it normallyIf there is a negative and a positive ,change it to addition and switch the SECOND integer sign
When you do your homework at home.
They are inverse operationsalso you can think of subtracting as just adding a negative number.
Multiplication is the same as repeated addition. For example 12 * 3 = 12 + 12 + 12 12 * 4 = 12 + 12 + 12 + 12 and so on.
When you can do addition and subtraction without recourse to it. Then it simply becomes a distraction.
They have an inverse relationship. 3 + 4 = 7 7 - 4 = 3
