Stefan completes this calculation. 95 take away 67 equals 28. Write an addition he could use to check his answer.

So in this problem, we’re told that Stefan completes a subtraction. And we’re asked to find an addition that Stefan could use to check that he subtracted correctly. This question is all about understanding how subtractions and additions work.

We know that, with a subtraction, we start with the whole amount. In this case, Stefan starts with 95. And then, we subtract part of it. Stefan subtracts 67. And so what’s left is the remaining part. Stefan can check his answer by adding it to 67. If the answer to his addition is the same as the whole, in other words, if 28 plus 67 equals 95, then he knows his answer is correct.

So Stefan could use the addition 28 plus 67 equals 95. This addition is the inverse of the subtraction that Stefan worked out. So the addition that Stefan could use is 28 plus 67 equals 95. And because we know that numbers can be added in any order to give the same total, it would also be correct to write 67 plus 28 equals 95.
