World Maths Day Stats

You can’t calculate a googolplex

No, this isn’t a Google drawing! A googolplex references the power of 10 to the power of 100. (If you weren’t sleeping in high school math class, you might remember this.) Unfortunately, you can’t calculate this on your calculator or computer because the answer is so long, you’ll run out of space!

Think about this next summer when you hear the cicadas

You know those noisy insects, the cicadas? Their mating ritual and incubation periods can keep cicadas underground for either 13 or 17 years. 13 and 17 are prime numbers that biologists say have influenced the insects’ ability to avoid predators with more even-numbered life-cycles.

Speaking of prime numbers, let’s consider 2 and 5

In case you forgot, a prime number is an integers or whole number that is divisible only by 1 and itself. The prime numbers, 2 and 5, are the only numbers that end in…wait for it…2 and 5!
