2 * 7 - 10 / 9 - 4 =
I got 7. Is that ok?
not the way you typed it
If you meant
2*7 - 10/(9-4)
= 14 - 10/5
= 14 - 2
= 12
45/8(5-4)-3
To correctly solve the expression 2 * 7 - 10 / 9 - 4, you need to follow the order of operations, which is often represented by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division - from left to right, Addition and Subtraction - from left to right).
Let's break down the expression step by step:
1. First, perform any operations within parentheses. There are no parentheses in this expression.
2. Next, evaluate any exponents. There are no exponents in this expression.
3. Then, calculate any multiplication and division from left to right:
2 * 7 = 14
10 / 9 = 1.11 (rounded to two decimal places)
So far, the expression is now: 14 - 1.11 - 4.
4. Finally, calculate the addition and subtraction from left to right:
14 - 1.11 = 12.89 (rounded to two decimal places)
12.89 - 4 = 8.89 (rounded to two decimal places)
Therefore, the correct answer to the expression 2 * 7 - 10 / 9 - 4 is approximately 8.89.
Since you mentioned that you got 7, it seems there might be an error in your calculations. Try re-evaluating each step and double-checking your calculations to find the mistake.
