To determine the result of the expression 30 - 4, we perform a simple subtraction operation.

Starting with the number 30, we subtract 4 from it. When you take 4 away from 30, you are essentially finding out how much remains after that quantity is removed.

30 - 4 equals 26. This confirms that the total remaining after subtracting 4 from 30 is indeed 26. Understanding basic subtraction is fundamental in math, especially when it comes to solving problems where calculations are involved, such as those encountered in the Firefighter Testing System.
