Is it addition and subtraction before multiplication and division?
Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. After computing within the grouping symbols, divide or multiply from left to right and then subtract or add from left to right.
Why are multiplication and division done before addition and subtraction?
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 order of operations for solving inequalities?
Reverse addition and subtraction (by subtracting and adding) outside parentheses. Reverse multiplication and division (by dividing and multiplying) outside parentheses. When multiplying or dividing by a negative number, flip the inequality sign. It does not matter if the number being divided is positive or negative.

What are the rules for solving linear inequalities?
Operations on linear inequalities involve addition, subtraction, multiplication, and division. The general rules for these operations are shown below. Although we have used < symbol for illustration, you should note that the same rules apply to >, ≤, and ≥.
How does subtracting both sides of an inequality change the inequality sign?
Subtracting both sides of the inequality by the same number does not change the inequality sign. For example, if a< b, then a – c < b – c. Multiplying both sides of an inequality by a positive number does not change the inequality sign. For example, if a< b and if c is a positive number, then a * c < b *
