David did 56 more push-ups than Zachary in gym class today. If David did 38 push-ups how many push-ups did Zachary and David do altogether?
First, we need to find the total number of push-ups that David and Zachary did together. We know that David did 38 push-ups, and we know that Zachary did 56 more push-ups than David, so we can say that Zachary did 38 + 56 = 94 push-ups. 

Now, we need to find the total number of push-ups that David and Zachary did together. We know that David did 38 push-ups and Zachary did 94 push-ups, so we can say that the total number of push-ups that David and Zachary did together is 38 + 94 = 132 push-ups. 

Therefore, the answer (numeric) is: 

132
