Expressions with-parentheses. Fill in the missing numbers. Level 2.

Parentheses — ( ), in math, are often used to group together parts of an expression. This helps you to find the order of precedence when you work with equations. Complex, multi-step equations often require multi-step solutions. When it comes to evaluating expressions that contain parentheses, you can follow these steps:

  1. Evaluate the contents of parentheses, from the inside out.
  2. Evaluate the rest of the expression.

(4 ÷ __) × (1 × __) = 2 × 9 = 18

(2 × __) – (__ × 4) = 12 – 4 = 8

(1 + __) – (1 × __) = 10 – 6 = 4
