Operations and Equations with Numbers

The video tutorial explains how to make equations true using parentheses and basic arithmetic operations. It demonstrates solving two equations: forming 30 by using multiplication, subtraction, and division, and forming 48 by using addition and multiplication. The tutorial encourages students to apply these methods to solve additional equations on their own.

How can you use parentheses to make the equation 5 times 6 equal 30?

• (5 * 6)

• 5 + (6 - 1)

• (5 + 6) * 1
