What is an expression?
Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations. As an illustration, the expression x + y has the terms x and y with an addition operator between them.
In this case 1 1/4 - 3/8 will be:
= 1 1/4 - 3/8
= 1 2/8 - 3/8
= 7/8
Check:
7/8 + 3/8
= 10/8
= 1 1/4
This is confirmed to be correct.
