While we’re on the topic of math, we might as well talk about one more problem with you guys. If a woman is pregnant with twins, how long (on average) will she carry them to term? Obviously, the answer is nine months. Don’t ask us how, that’s just the way it is.
If you’re wondering why it’s not 18, you don’t carry each baby for nine months. One of the twins doesn’t chillax in the womb while waiting for its sibling to develop. They grow at the same time! Now, if you’re wondering why it’s not 19, we don’t have an answer for you.
