Balance Addition Equations up to Three Digits
Consider the addition equation:
___ + 165 = 160 + 147
Let's identify the missing addend to complete this equation.
To find the missing addend,
first, we need to find 160 + 147.
| ? | + | 165 | = | 160 | + | 147 |
| ? | + | 165 | = | 307 |
Now, to find the missing addend we need to calculate 307 – 165.
Subtract:
307 – 165 = 142
The missing addend is 142.
