P-paratheses (do any math that has parentheses around the numbers) y=(2x5)+25 E-exponents (do the exponents next) y=(2x5)+5^2 M-multiplying. (Basically everything is self explanatory from here to then cuz im lazy to list examples) Just basically if you don't use PEMDAS, you'll get the wrong answer
Let's make an equation. T will be the number. (T+5)/4=7 Let's multiply both sides by 4 to get T by itself. T+5=28 Subtract 5 from both sides. T=23 Your number is 23.
