I'm I supposed to add or subtract. Please help!

those are supposed to absolute value symbols, right? abs. value of 4 is 4 abd abs. value of -3 is 3. so...4+3=7

Thank you!

You're welcome! Yes, those symbols represent absolute value. Absolute value is a mathematical operation that gives the positive magnitude of a number. In this case, the absolute value of 4 is 4 and the absolute value of -3 is also 3. Since you have to add these two absolute values together, the sum would be 4 + 3, which equals 7.
