To find the number from which you can subtract half and end up with zero, we can set up a simple equation. Let’s call the unknown number X. According to the problem, when you subtract half of this number from itself, you should get zero. We can express this mathematically as:
X – (1/2)X = 0
Now, simplifying the left side of the equation:
(1 – 1/2)X = 0
This simplifies to:
(1/2)X = 0
Now, to solve for X, we can multiply both sides by 2:
X = 0
So, the number you can subtract half from to obtain a result of zero is 0.
It’s a straightforward solution, but it’s fascinating how in mathematics, zero plays such a unique role. It’s the only number that, when halved, remains unchanged, and subtracting half of it brings you right back to where you started!
