Reverse Connection

An Advanced Mathematics Lesson Starter Of The Day

Choose any two digit number (E.g. 37)

Reverse the order of the digits (E.g. 73)

Find the difference between the two numbers (E.g. 73 - 37 = 36)

Repeat this operation for many different two digit numbers. Do you notice any connection between the answers? Can you explain the reason for this connection using algebra?
