CalculationX20 / 計算20

Reminds me of the times as a kid in school where the teacher would give these tests out, and I would always race to finish first 😆.

Math is a workout for the brain, and it pays off (Geometry can aid in drawing, music theory as Pythagoras tells us can be defined as the sound of numbers, literature involves a kinda rhythm or tempo i.e. numbers, just about everything!) Good stuff.

Really nice idea

My son will love this

Wait.....Did i just do someones homework in Dreams?
