Answer 2

To solve the expression (287:7+243)-91:7+43, we need to follow the order of operations, which is typically remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's break down the expression step by step:

1. Perform the division first: 287 ÷ 7 = 41

   (287:7+243)-91:7+43 = (41 + 243) - 91:7 + 43

2. Perform the addition within the parentheses: 41 + 243 = 284

   (284 - 91:7 + 43)

3. Perform the division: 91 ÷ 7 = 13

   (284 - 13 + 43)

4. Perform the remaining addition and subtraction from left to right: 284 - 13 + 43 = 314

Therefore, the value of the expression (287:7+243)-91:7+43 is 314.
