How to Calculate the Number of Subtractions
Let the minuend be \( A \), and the subtractor be \( B \). To find how many complete times \( A \) can be reduced by \( B \), follow these steps:
Set Up the Equation: When subtracting \( B \) repeatedly from \( A \), the condition is: \( A - n \times B \geq 0 \), where \( n \) is the number of complete subtractions.
Determine \( n \): Use integer division to calculate how many full subtractions are possible:
\( n = \left\lfloor \frac{A}{B} \right\rfloor \)
Here, the integer part of the division result represents the total number of full subtractions. The remainder (if any) is the part of \( A \) that cannot be further reduced by \( B \).
Examples
Example 1: How many times can be subtract 10 from 100?
Solution:
\( n = \frac{100}{10} = 10\)
Result: You can subtract 10 times.
Example 2: How many times can be subtract 28 from 1320?
Solution:
\( n = \frac{1320}{28} = 47…4\)
Result: You can subtract 47 full times, with a remainder of 4.
Example 3: How many times can be subtract 8 from 2560?
