Supply the missing operator.
3 = 12 9 |
Supply the missing operator.
6 3 = 18 |
|
Step 1: Compare operand 1 and answer |
|
If operand 1 is larger than the answer, then the operation is either subtraction or division.
Since 12 > 3, the operation is either subtraction or division. |
If the operand 1 is smaller than the answer, then the operation is either addition or multiplication.
Since 6 < 18, the operation is either addition or multiplication. |
|
Step 2: Try the two operators |
|
3 = 12 - 9? |
Yes! |
3 = 12 ÷ 9? |
No |
|
6 + 3 = 18? |
No |
6 × 3 = 18? |
Yes! |

Answer: |
3 = 12 9 |
6 3 = 18 |
