Balancing with mixed operations I
Lesson

In Balancing Numbers up to 50 we saw that number sentences are balanced if both sides of the number sentence have the same value.  

Example: $20-4=13+3$204=13+3

In this number sentence both the left and right sides of the sentence are equal to $16$16.  So we say the number sentence is balanced.  

Look at this video to see how to solve maths problems involving balancing number sentences.

 

Worked Examples

Question 1
