Question

evaluate the expression.
-0.7 + 0.9 + -0.4 × 0.5
write your answer as an integer or a de

Explanation:

Step1: Perform multiplication first

According to the order of operations (PEMDAS/BODMAS), we first calculate the multiplication part: \(-0.4 \times 0.5\).
\(-0.4 \times 0.5 = -0.2\)

Step2: Perform addition from left to right

First, add \(-0.7\) and \(0.9\): \(-0.7 + 0.9 = 0.2\)
Then, add the result to \(-0.2\): \(0.2 + (-0.2) = 0\)

Answer:

\(0\)
