Answer
$95$
Work Step by Step
The order of operations follow the following hierarchy (PEMDAS rule):
(i) Parentheses/grouping symbols
(ii) Exponents
(iii) Multiplication/Division, whichever comes first from the left
(iv) Addition/Subtraction, whichever comes first from the left
Use the rule above to obtain:
$=100-100 \div 25 \cdot 2 -(-3)
\\=100-4 \cdot 2 -(-3)
\\=100-8 +3
\\=92+3
\\=95$
