Zachary did 46 push-ups and 58 crunches in gym class today. David did 38 more push-ups but 62 less crunches than zachary. How many more crunches than push-ups did Zachary do?
First, we need to find the total number of push-ups that Zachary and David did. Zachary did 46 push-ups and David did 38 more push-ups than Zachary, so we can say that the total number of push-ups is 46 + 38, which is 84. 

Next, we need to find the total number of crunches that Zachary and David did. Zachary did 58 crunches and David did 62 less crunches than Zachary, so we can say that the total number of crunches is 58 - 62, which is -4. 

Now, we need to find the difference between the total number of push-ups and the total number of crunches. The total number of push-ups is 84 and the total number of crunches is -4, so the difference is 84 - (-4), which is the same as 84 + 4, which is 88. 

Therefore, the answer (numeric) is: 

88
