Studdy Solution

STEP 1

1. The problem involves a sequence of arithmetic operations.
2. We need to evaluate the expression step by step.
3. The operations should be performed from left to right.

STEP 2

1. Evaluate the expression from left to right.
2. Simplify the expression to find the final result.

STEP 3

Start by evaluating the first operation: 7−13 7 - 13 .
7−13=−6 7 - 13 = -6

STEP 4

Use the result from STEP_1 and perform the next operation: −6+21 -6 + 21 .
−6+21=15 -6 + 21 = 15

STEP 5

Use the result from STEP_2 and perform the next operation: 15−36 15 - 36 .
15−36=−21 15 - 36 = -21

STEP 6

Use the result from STEP_3 and perform the final operation: −21+42 -21 + 42 .
−21+42=21 -21 + 42 = 21
The final result of the expression is:
21\boxed{21}
