Times to Subtract Calculator – How Many Times Can be Subtracted

Welcome to the Times to Subtract Calculator, which is used to calculate how many times a given number can be subtracted from another. For example, How many times can 10 be subtracted from 100?

First of all, what is the endpoint of the subtraction?

Negative number or zero?

If it is a negative number that is not specified, the times of subtractions will be infinite.

Therefore, we calculate the times of subtractions, whose final result is 0. That is, after subtracting multiple times, the result is 0.

So, the full description of the question should be: How many times can 10 be subtracted from 100 and the final result is 0?

How to solve it?

Two common methods are subtraction and division.

Subtraction Method

Descending sequentially until 0 or a negative number.

As in the example above

100 – 10 = 90

90 – 10 = 80

80 – 10 = 70

70 – 10 = 60

60 – 10 = 50

50 – 10 = 40

40 – 10 = 30

30 – 10 = 20

20 – 10 = 10

10 – 10 = 0

So, the answer is 10 times. This method is simple but has a fatal flaw. If the number is large, multiple calculations are required.

Division Method

Divide the subtracted number by the subtrahend directly.

If the remainder is 0, then the quotient is the times to subtract. If the remainder is greater than 0, then adding 1 to the quotient is the times we want.

For example, How many times can 10 be subtracted from 100?

10010 = 10

100 is divisible by 10, the quotient is 10.

So, there are 10 times you can subtract 10 from 100.

Another example, how many times can 8 be subtracted from 33?

With the Quotient and Remainder Calculator, we can know that when 33 is divided by 8, the quotient is 4, and the remainder is 1.

338 = 4…1

The remainder is greater than 0, so add 1 to the quotient.

Thus, subtract 8 from 33, you can subtract 5 times.

Of course, there are other methods, such as arithmetic sequence and so on, which will not be described in detail here. If possible, it is recommended to use the Times to Subtract Calculator on the page directly, enter the number and you can get the answer immediately.

Next, we will introduce how to use the calculator.

Using the calculator is simple, follow these 3 steps:
