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.

It is difficult to answer the question because, for addition or subtraction, it is often easier to obtain the exact answer! If you line up the decimal points and then follow the rules of addition or subtraction - exactly as they would apply to whole numbers - you will get the correct answer!Estimation may be useful to check your answer if you are poor at addition or subtraction of integers. But, if that is the case, your estimate is equally likely to be wrong!
Arithmetic (watch the spelling) refers to the basic math taught in primary school: addition, subtraction, multiplication and division of integers, fractions, and decimals.

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

The multiplication and division will have a rule that if both integers are negative the answer will be positive but if one of the integers is negative and other is positive, the answer will be negative. In addition and subtraction this will not be happen.
Multiplication is the same as repeated addition. For example 12 * 3 = 12 + 12 + 12 12 * 4 = 12 + 12 + 12 + 12 and so on.
They have an inverse relationship. 3 + 4 = 7 7 - 4 = 3
