10    10    10    10=101 \large 10\; \Box\; 10\; \Box\; 10\; \Box\; 10=101

Is it possible to fill each square in with an arithmetic operation (+,,×,÷) (+, -, \times, \div) so that this becomes a true equation?

You'd be surprised how many people forget about the order of operations...

Bonus question: Replace 101 with another number between 0 and 200 that makes this problem impossible.
Difficult follow-up bonus: How many different numbers is it possible to make with four 10's and three arithmetic operations?
