Mental subtraction of 2-digit numbers (SET 2) | Karteikarten

Karteikarten von Bruce Akitt, erstellt am more than 1 year ago

When dividing by a single digit number, finding the remainder often requires subtraction of two 2-digit numbers whose difference will be a number less than 10. This is best done by using addition with the remainder being the one digit number that you would add to the quotient to make the dividend. These flashcards practice this mental calculation, where the difference is between 5 and 8..
