Consider the equation:
12 + 2 = 17 – __
Let's identify the missing number that makes the equation true.
To identify the missing number, first we need to add 12 + 2:
12 + 2 = 17 – __
14 = 17 – __
Now, let’s look for the number which when subtracted from 17 gives 14.
14 = 17 – 3
12 + 2 = 17 – 3
So, the missing number is 3.
