-10/-2-3(-10-2) Since m=-10 and n=-2, we substitute them in for the values since they have an equal relationship.
Now, follow Orders of Operations: PEMDAS
-10/-2-3(-12) Simplify parentheses (P) There are no Exponents (E) Multiplication (M) and Division (D) are =, so we do whatever operation comes from the left to right. -10/-2=5 Division comes first on the left. therefore: 5-3(-12)
-3(12)=-36, Multiplication is last on the right. therefore: 5-36
5-36=-31 After M/D, we do Addition and Subtraction, which are also =, so we do them left to right.
