To simplify the expression 12815 − 7 + 715 + 15, we need to follow the order of operations, which is often remembered as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
In this expression, there are no parentheses, exponents, or multiplication/division operations, so we only need to perform addition and subtraction.
Starting from the left, we can evaluate the expression step by step:
1. Start with 12815 − 7 = 12808.
2. Add 715 to the result: 12808 + 715 = 13523.
3. Finally, add 15 to the previous result: 13523 + 15 = 13538.
Therefore, the simplified answer to the expression 12815 − 7 + 715 + 15 is 13538.
