Math CWK #1 PEMDAS

Using ALL the numbers 1, 2, 3, 4, & 5 (only once) and the Orders of Operations (PEMDAS), try to write equations that have the numbers from 1 to 100 as the answer. Only single digit numbers allowed.

Parentheses, Exponents, Multiplication & Division, Addition & Subtraction

Rule 1: Simplify all operations inside parentheses.

Rule 2: Simplify all exponents, working from left to right.

Rule 3: Perform all multiplications and divisions, working from left to right.

Rule 4: Perform all additions and subtractions, working from left to right.

Example*: Solving for zero. 0 = [3 - (1+2)] x 4 x 5 * Note: There can be multiple solutions.
