Question

Unscramble the steps and show them in the correct order to find the value of the expression:

a) 1
b) -3
c) 12.4 - 3
d) -12.4

Answer 1

To find the value of the expression, follow the order of operations (PEMDAS).

Step-by-step explanation:

To find the value of the expression, you need to follow the correct order of operations, which is also known as PEMDAS. This stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

1. First, perform any calculations inside parentheses.
2. Next, evaluate any exponents.
3. Then, perform multiplication and division from left to right.
4. Finally, perform addition and subtraction from left to right.

Applying these steps to the expression, you would perform the operations in the order given:

12.4 - 3 = 9.4

9.4 - (-12.4) = 21.8.
