Why is multiplication done before addition?
Students should have answered something in their own words that gets across the concept: Multiplication and division are done before addition and subtraction in order to convert groups of items into subtotals of like items that can be combined for the total.
What is the answer 5 5×5 5?
Using order of operations or PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction, from left to right) -5×5 goes first resulting in -25. You’re equation will be: 5–25+5. Using order of operations further solve: 5–25= -20. The equation will now be -20+5 your final answer will be -15.
Do you square first or multiply?
