Perform the operations inside the brackets first, then complete the simple addition and subtraction from left to right to solve in under 10 seconds.
Students often perform operations strictly from left to right (2.5 * 4 + 12 / 3 - 2) ignoring the brackets, or perform subtraction before addition, leading to incorrect results.
Simplify terms inside brackets
First, solve the multiplication inside the first bracket and the division inside the second bracket.
(2.5├Ч4)=10,(12├╖3)=4
Substitute values into the expression
Replace the calculated bracket values back into the main expression.
