The square of a number is found by multiplying it by itself. The square of a number in an algebraic expression is shown using an exponent of 2. For a number represented by n, the square of the number is n².
3 less than a number is found by subtracting 3 from the number. Equivalently, it is found by adding -3 to the number. The addition can be done in any order. For a number represented by n, 3 less than the number is either of ...
-3 +n
n -3
