Question

What is the mathematical definition of the Subtraction Property of Equality?

Answer 1

I just learned this today.

In my case, You can add or subtract the same quantity from both sides and retain the equality.

For example: If
`a=b`, then
`a-c=b-c`

Additive and Subtractive Property of Equality are the Same Thing
