Answer
89
Work Step by Step
Use the order of operations to simplify the expression:$$10^[2]-100\div5^[2]\times2-3$$
As there are no grouping symbols, start with exponents$$=100-100\div25\times2-3$$
Next complete all multiplication and division in the order it appears left to right$$=100-4\times2-3$$ $$=100-8-3$$
Finally complete all addition and subtraction in the order it appears left to right$$=92-3$$ $$=89$$
