In addition and subtraction, start calculations from the rightmost digit.
1
In math addition and subtraction, start at the last digit and work your way to the left, digit by digit, until the calculation is complete.
2
Calculate the Ones digit 7 - 1, the result is 6. Write the result 6 below the vertical form.
HundredsTensOnes-3396716A more intuitive calculation method is to use a number line, where the point representing a number on the number line increases from left to right and decreases from right to left. Therefore, subtraction can be performed by moving to the left along the number line.1.Calculate 7 - 1, the result is 6.The point representing 7 on the number line is moved 1 units to the left along the number line, and the result is 6.012345(1)6789101112(1)The point representing 7 on the number line is moved 1 units to the left along the number line, and the result is 6.

Calculate the Hundreds digit 3 - 3, the result is 0. Write the result 0 below the vertical form.
HundredsTensOnes-339671036A more intuitive calculation method is to use a number line, where the point representing a number on the number line increases from left to right and decreases from right to left. Therefore, subtraction can be performed by moving to the left along the number line.1.Calculate 3 - 3, the result is 0.The point representing 3 on the number line is moved 3 units to the left along the number line, and the result is 0.-5-4-3-2-101(1)2345678(1)The point representing 3 on the number line is moved 3 units to the left along the number line, and the result is 0.
3
When 0 is in the highest place and has no actual value, it can be omitted.
4
Calculate 397 - 361. The result is 36.
