- That makes sense when you think about it like this.
You are 1. You = 1.
Person who has won = 1.
Person wins a second time = 1 + 1 = 2.
Person wins a second time = You * 2, or 1 * 2.
There are now twice as many people who have won twice than you are.
Written math doesn't follow regular grammatical rules, so it is intuitively harder to follow if you don't parse it out mathematically. Parsing it out grammatically will only end in confusion, and at times, incorrect calculations.
Another good grammar vs. mathematics example is:
Seven and two is nine.
That is incorrect grammar, because you would say, "Seven and two are
nine". Just like saying "apples and raspberries are red". Apples are red, and raspberries are red. But seven is not nine, and two is not nine, so the grammatically correct version is mathematically incorrect.
The moral of the story: when reading mathematical explanations, don't use your understanding of grammar to understand it; instead, use your understanding of mathematics.
