Answer:
56
Step-by-step explanation:
Think of it this way, 7 times 10 is 70.
7*8 is 2 less 7s, or 14 less.
70-14=56
Or, a simpler way:
7*7 is 49(perfect square)
One more seven than that is 56.
These are just two ways I quikcly remember, because for some reason I struggle with 7 and 8 mulitplication.
Hope this helps!
