Solution

The correct option is A
74

$12 + 22 \div 11 \times (18 \div 3)^{2} - 10$
$= 12 + 22 \div 11 \times 6^{2} - 10$ (Brackets first)
$= 12 + 22 \div 11 \times 36 - 10$ (Exponents)
$= 12 + 2 \times 36 - 10 = 12 + 72 - 10$ (Division and multiplication, left to right)
$= 84 - 10$
$= 74$ (Addition and subtraction, left to right)
