What do you mean by difference? Mathematical symbols.
Subtract-Subtract = The difference is subtracted before and after.

Example: 3-2= 1 3 is the minuend, 2 is the reduction, and 1 is the difference.

Of course, the minuend is not necessarily larger than the subtrahend, such as 2-3=- 1, where 2 is the minuend, 3 is the subtrahend, and-1 is the difference.

Extended data:

Subtraction is one of the basic operations in mathematics. Two numbers a and b are known. If there is a number c that satisfies b+c=a, then c is called the difference between a and b (and the difference is unique). The operation of finding the difference between two numbers is called subtraction, which is recorded as a-b=c, and pronounced as A minus B equals C, A is called the minuend, and B is called the minus sign.

Subtraction can be defined as the operation of finding the other addend by knowing the sum of two addends and one of them. In arithmetic that can only use positive numbers, the minuend cannot be less than subtraction. Especially, for any number a, there are always a-a=0, a-0=a, and 0-0=0. After introducing negative numbers and negative signs, subtraction can be unified with addition, that is, a-.

(1) Primary example: 10 (minuend)-(minus sign) 6 (subtraction) = (equal sign) 4 (difference)

(2) Advanced example: If the result of addition, subtraction and difference of the minuend is 42, what is the minuend?

Solution: Let the minuend be A, the minuend be B and the difference be C.

Move all the variables in the formula (1) to the left, and you get

Let's start with the addition of (2) and (3), and find that B and C are eliminated, then. Then the minuend is 2 1.
