Question

2+2×2-7+6+9÷4+7-5×10

Answer 1

Решение:
$\displaystyle \tt 2 + 2 \times 2 - 7 + 6 + 9 \div 4 + 7 - 5 \times 10 = 2 + 4 - 7 + 6 + 2.25 + 7 - 50 = 12.25 - 50 = - 37.75$

Answer 2

To solve the expression, you need to follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Here's the step-by-step calculation:

1. Start with multiplication and division from left to right: 2 + 2 × 2 - 7 + 6 + 9 ÷ 4 + 7 - 5 × 10 = 2 + 4 - 7 + 6 + 2.25 + 7 - 50

2. Now, perform the addition and subtraction from left to right: = (2 + 4) - 7 + 6 + 2.25 + 7 - 50 = 6 - 7 + 6 + 2.25 + 7 - 50 = -1 + 6 + 2.25 + 7 - 50 = 7.25 + 2.25 - 50 = 9.5 - 50 = -40.5

So, the result of the expression is -40.5.
