When the expression contains parentheses for example: 3-10 +(9×7) +2 you should do all the operations inside the parentheses first and then continue with the rest of the expression is this true or false?

Answer 1

True. According to the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), you should perform calculations inside parentheses first. So in the expression \(3 - 10 + (9 \times 7) + 2\), you would first calculate \(9 \times 7\), then proceed with the other operations in the correct order.
