Antimatter

In my opinion this form of matter is one of the most fascinating things in the universe.
Antimatter is created by colliding an antielectron (a positron, or an electron with a positive charge) and a antiproton (a proton with a negative charge) which gives you antihydrogen (or antimatter). So as you can see antihydrogen is created in the same way that regular hydrogen is created. The same principal applies with positive and negtive numbers when you add two negatives together you get a higher negative number and when you add two positives together you get a larger positive number. But when you add for example -3 plus 3 you get zero ( just like if you add equal amounts of matter and antimatter they anielate eachother.) So if you add for example -3 plus 1 you get -2 ( so in theory if you added three atoms of antimatter and one regular atom you would have two atoms of antimatter left)
