Consider the equation:
91 – __ = 7 + 74
Let's identify the missing number that makes the equation true.
To identify the missing number, first we need to add 7 + 74:
91 – ? = 7 + 74
91 – ? = 81
Now, to find the missing number we need to calculate 91 – 81.
91 – 81 = 10
91 – 10 = 7 + 74
So, the missing number is 10.
