Calculate the Ones digit 8 - 8, the result is 0. Write the result 0 below the vertical form.
HundredsTensOnes-9394880A 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 8 - 8, the result is 0.The point representing 8 on the number line is moved 8 units to the left along the number line, and the result is 0.-5-4-3-2-10123456(1)78910111213(1)The point representing 8 on the number line is moved 8 units to the left along the number line, and the result is 0.
