Let a square equal three, so a square multiplied by two equals six. What number does a triangle equal if four multiplied by a triangle equals 12?

In this problem, some of the numbers have been replaced by shapes. And each shape has a value. We’re told that the square is worth three. So we know that in the calculation, square multiplied by two, we know the answer is going to be six because the square is worth three. And three times two is six.

Let’s look at the rest of the problem. What number does a triangle equal if four multiplied by a triangle equals 12? Once again, we’re given a shape that represents a value. This time, it’s a triangle. Four multiplied by a triangle equals 12. What do we multiply four by to get 12? Four multiplied by three equals 12. And so the number that the triangle equals is three.
