Substitute given values: First, we need to substitute the given values of y and z into the expression. So we replace y with 1.46 and z with 3.82. The expression becomes: −1.46+(−3.82)+7.99.
Perform addition and subtraction: Next, we need to perform the addition and subtraction in the expression. We start by adding the negative numbers: −1.46 and −3.82.−1.46+(−3.82)=−1.46−3.82=−5.28.
Final calculation: Now, we add the result from the previous step to 7.99. −5.28+7.99=2.71.
