Calculation Details
111 and 75 are all positive numbers.
When subtracting two positive numbers, you can directly subtract number to subtract from the number being subtracted and keep the sign unchanged.
1
In vertical addition or subtraction, ensure that digits with the same place value are aligned.
1
The same digits must be aligned, usually starting from the ones digit; when calculating addition and subtraction of decimals, the decimal points must be aligned first.
2
Align the Ones digits 1 and 5.

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.

Calculate 1 - 5 in the Ones place. Since 1 is less than 5, it is not enough to subtract. We need to borrow 1 from the higher place value and treat it as 10. After borrowing, the Ones digit becomes 11. Next, calculate 11 - 5, the result is 6. Write the result 6 below the vertical form.
HundredsTensOnes-1171156A 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 1 - 5 in the Ones place. Since 1 is less than 5, it is not enough to subtract. We need to borrow 1 from the higher place value and treat it as 10. After borrowing, the Ones digit becomes 11.The point representing 1 on the number line is moved 10 units to the right along the number line, and the result is 11.2.Next, calculate 11 - 5, the result is 6.Continue moving 5 units to the left along the number line, and the result is 6.-9-8-7-6-5-4-3-2-10(1)123456789(2)10111213141516(1)The point representing 1 on the number line is moved 10 units to the right along the number line, and the result is 11.(2)Continue moving 5 units to the left along the number line, and the result is 6.

Calculate 1 - 7 in the Tens place. Since 1 is less than 7, it is not enough to subtract. We need to borrow 1 from the higher place value and treat it as 10. After borrowing, the Tens digit becomes 11. From the Tens place 11, 1 was borrowed, leaving 10. Next, calculate 10 - 7, the result is 3. Write the result 3 below the vertical form.
