What is 22+-9-9+7=
29
The two adjacent math signs are confusing. It can be clarified by adding parentheses.
22+(-9-9+7) = 22+(-11) = 11
Or do you mean:
22±9-9+7 which would give you 11 for the negative term and 29 for the positive aspect.
I hope this helps. Thanks for asking.
To solve the arithmetic expression 22 + (-9) - 9 + 7, we can follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
Step 1: Deal with parentheses and other grouping symbols. In this case, there are no parentheses, so we move to the next step.
Step 2: Perform exponents if any. There are no exponents in this expression.
Step 3: Perform multiplication and division from left to right. There are no multiplication or division operations in this expression.
Step 4: Perform addition and subtraction from left to right. Let's break down the expression:
22 + (-9) - 9 + 7
First, we'll add 22 and -9:
22 + (-9) = 13
Then, we'll subtract 9 from 13:
13 - 9 = 4
Finally, we'll add 4 and 7:
4 + 7 = 11
Therefore, the value of the expression 22 + (-9) - 9 + 7 is 11.
