Ответ:
for this expression, you need to start with the innermost parentheses and work your way out--do (3 + 1) FIRST, then worry about what's inside the [square brackets].
2 × {6 + [12 ÷ (4)]} - 1 ... now divide 12 by 4
2 × {6 + [3]} - 1 ... now add 6 and 3
2 × {9} - 1
now follow the order of operations, PEMDAS. multiply first, then subtraction second:
2 × 9 - 1 ... multiply 2 and 9
18 - 1 ... subtract
17 is your result.
