Negative Remainder Theorem and its Application

Say, a number 37 is divided by 7 then what would be the remainder? Yes, 2 is the actual remainder which is also a positive remainder. It also gives a negative remainder. The negative remainder would be -5. See, the positive remainder is 2 which are just more than 35 and -5 is just less than 42. Notice, 35 and 42 is divisible by 7.

Unit Digit theorem and its applications

Unit digit theorem is just extension of Remainder Theorem but the change is that you always need to divide given expression by 10 to find its unit digit. On the logic of remainder theorem, the unit’s digit of an expression will be taken by getting the remainder when the expression is divided by 10.
