suggest using the order of operations (PEMDAS) to simplify this expression.
First, we need to simplify what's inside the parentheses:
- (–0.6 – (–0.8)) = –0.6 + 0.8 = 0.2
Next, we can multiply by 2:
- 2 × 0.2 = 0.4
Now, we can add 0.9 to this result:
- 0.9 + 0.4 = 1.3
Therefore, the value of the expression is 1.3.
To evaluate the expression 0.9 - 2 × ( - 0.6 - (-0.8) ), we follow the order of operations (also known as PEMDAS/BODMAS).
1. Simplify the expression inside the parentheses:
- 0.6 - (-0.8)
= - 0.6 + 0.8
= 0.2
2. Multiply 2 by 0.2:
2 × 0.2
= 0.4
3. Subtract 0.4 from 0.9:
0.9 - 0.4
= 0.5
Therefore, the value of the expression is 0.5.
