(b) 796 – 314

Answer 1

AnSweR:-

• 728+996 = 1724
• 796-314 = 482

→ Addition (usually signified by the plus symbol +) is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division. The addition of two whole numbers results in the total amount or sum of those values combined.

→ In mathematics, subtraction means to take away some things from a group. In other words, subtraction is the process of removing things from a group. We use minus sign (-) as the subtraction symbol when one number is subtracted from another number.
