FAQ

Everything you need to know about this question

How do I know which number goes where in the subtraction?

+

Look at the structure of the problem! In 62 - □ = 55, the 62 is the starting number (minuend), the box is what you take away (subtrahend), and 55 is what's left (difference).

Why can't I just guess and check with the answer choices?

+

While guessing might work sometimes, understanding the method helps you solve any similar problem confidently. Plus, you'll be faster and more accurate!

What if the missing number was in a different position?

+

Great question! If it was □ - 7 = 55, then □ = 55 + 7 = 62. The position of the missing number determines which operation you use to solve.

How can I check if my answer is correct?

+

Always substitute your answer back into the original equation. Replace the box with your answer and see if both sides are equal: 62 - 7 = 55 ✓

Is there a pattern I can remember for these problems?

+
  • Missing subtrahend: a - □ = c, so □ = a - c
  • Missing minuend: □ - b = c, so □ = b + c
  • Missing difference: a - b = □, so □ = a - b
