To evaluate the expression (8/2)+23−5, we divide 8 by 2 first, resulting in 4. Then we add 4 to 23, giving us 27. Finally, we subtract 5 from 27, giving us 22. Therefore, the evaluation of the expression is 22.
there is no 22
Apologies for the mistake. Let's evaluate the expression correctly.
(8/2) + 23 - 5
First, we simplify the division: 8 divided by 2 equals 4.
Now we have: 4 + 23 - 5
Next, we perform the addition: 4 + 23 equals 27.
Now we have: 27 - 5
Finally, we perform the subtraction: 27 - 5 equals 22.
Therefore, the evaluation of the expression (8/2) + 23 - 5 is 22.

To simplify the expression 17⋅2−42+6, we need to follow the order of operations (PEMDAS).
First, we perform the multiplication: 17⋅2 equals 34.
Now the expression becomes 34 - 42 + 6.
Next, we do the subtraction: 34 - 42 equals -8.
Now the expression becomes -8 + 6.
Finally, we do the addition: -8 + 6 equals -2.
Therefore, the expression 17⋅2−42+6 simplifies to -2.

To solve the multi-step problem (1/2)⋅42−(4−6)/2, we need to follow the order of operations (PEMDAS).
First, we perform the multiplication: (1/2)⋅42 equals 21.
Now the expression becomes 21 - (4-6)/2.
Next, we do the subtraction inside the parentheses: 4 - 6 equals -2.
Now the expression becomes 21 - (-2)/2.
Then, we perform the division: -2 divided by 2 equals -1.
Now the expression becomes 21 - (-1).
Finally, we do the subtraction: 21 - (-1) equals 22.
Therefore, the solution to the multi-step problem (1/2)⋅42−(4−6)/2 is 22.
