Solving Decimal Arithmetic Problem
The problem requires calculating the value of the expression: $3.142 + 3.61 - 2.12 + 4 - 7.6$. We perform the operations step-by-step.
Step-by-Step Calculation
- First, group the positive and negative numbers:
- Positive numbers: $3.142, 3.61, 4$
- Negative numbers: $-2.12, -7.6$
- Sum the positive numbers: $3.142 + 3.61 + 4 = 10.752$
- Sum the absolute values of the negative numbers: $2.12 + 7.6 = 9.72$
- Subtract the sum of the negative numbers from the sum of the positive numbers: $10.752 - 9.72$
- Perform the final subtraction: $10.752 - 9.720 = 1.032$
The result of the calculation is $1.032$.
