Answer 2

To evaluate the expression 1/2 - (1/2)^2 * 2 + 2/3 - 25 * 0.03 * 4, we can follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Step 1: Evaluate the exponent (1/2)^2 = 1/2 * 1/2 = 1/4

The expression now becomes: 1/2 - 1/4 * 2 + 2/3 - 25 * 0.03 * 4

Step 2: Evaluate the multiplication 1/4 * 2 = 2/4 = 1/2 25 * 0.03 * 4 = 3 * 4 = 12

The expression now becomes: 1/2 - 1/2 + 2/3 - 12

Step 3: Evaluate the addition and subtraction from left to right 1/2 - 1/2 = 0 0 + 2/3 = 2/3 2/3 - 12 = -34/3

So, the final result of the expression 1/2 - (1/2)^2 * 2 + 2/3 - 25 * 0.03 * 4 is -34/3 or approximately -11.33.
