Subtraction Problems and Strategies

This video tutorial explains how to solve subtraction problems with missing numbers. It covers three examples: 12 - 3 = blank, 14 - blank = 8, and blank - 7 = 9. The video uses visual aids like drawing stars to represent numbers and demonstrates step-by-step how to find the missing values by counting and visualizing the subtraction process.

What is the main objective when solving subtraction problems with blanks?

• To find the missing number in the equation

• To divide numbers

• To add numbers together

• To multiply numbers
