Question

2+7(7-5*3):9+9*6= сколько будет

Answer 1

2+7×(7-5÷3)÷9+9×6=49.7777778

Answer 2

To solve the given mathematical expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's break down the expression step by step:

1. First, simplify the expression inside the parentheses: 7 - 5 * 3 = 7 - 15 = -8

2. Now, substitute the result back into the original expression: 2 + 7 * (-8) : 9 + 9 * 6

3. Perform multiplication: 2 + (-56) : 9 + 9 * 6

4. Continue with multiplication: 2 + (-56) : 9 + 54

5. Perform division: -54 : 9 + 54

6. Finally, complete the remaining addition and subtraction: -6 + 54 = 48

So, the result of the expression is 48.
