Question

247+(650-398+117)-386

Answer 1

247(650-398+117)-386=230

Answer 2

247+(650-398+117)-386=247+369-386=230

Answer 3

To solve this expression, we need to follow the order of operations, which is commonly remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). So, we first need to perform any operations inside parentheses, then exponents, then multiplication and division from left to right, and finally addition and subtraction from left to right.

Using this order of operations, we can simplify the expression as follows:

247 + (650 - 398 + 117) - 386 = 247 + (252 + 117) - 386 // Simplify the parentheses = 616 // Perform addition and subtraction from left to right

Therefore, the final answer is 616.
