Answer:
The answer to your question is - 8
Step-by-step explanation:
Data
(3 - 4) 2 * 5 + (4 - 1) 2/3
The order of operations is
1st Parenthesis
2nd Roots and exponents
3rd Multiplication and division
4rd Addition and subtraction
Following these rules
Parenthesis (-1) 2* 5 + (3) 2/3
Multiplication and division - 10 + (6/3)
- 10 + 2
Addition and subtraction - 8
