Advance Tips for Subtraction - When you are at the phase of solving advanced mathematics, then you can't waste time on getting stuck at subtraction. Thus, here present you some fast tricks with which you can subtract without any problem and continue with your further calculations. For instance, you have to subtract 94 from 212. Instead of subtracting them manually, you can add 6 to 94 to make it 100. Now, it becomes easy to subtract 100 from 212. The answer is 112, and then you can add 6 to the answer. You can further minimize your efforts by separating the problems into smaller parts for easier calculation. For instance, when you want to subtract 857 from 1,276. You can separate them into 1200 – 800 and 76 – 57. The first one's answer is 400, while the latter one's answer is 19. Now, you can add both answers together to get 419. These worksheets and lessons show students how to find the difference between three digit values.

Homework Sheets

Students can usually borrow pretty easy when it's two digits, but the move to three digits can overwhelm.

  • Homework 1 - It is always best to subtract starting at the lowest place value to the greatest place value.
  • Homework 2 - An example is provided for you to work off of.
  • Homework 3 - You will need to borrow at times, don't worry it is cool!



Practice Worksheets

We throw in a few tips with the practice sheets.

  • Practice 1 - Always start subtracting from the ones place (right). Work your way to the left as you move through the problem.
  • Practice 2 - A great way to check your work is to add the number you find as the difference to the number that you subtracted. You should get the starting number.
  • Practice 3 - If the number on top is smaller than the number on the bottom remember to borrow from the next place up.
