Multiplication Table: 144 squares, 78 answers, 36 facts to learn

A 12x12 multiplication table has 144 squares, but 7x8 and 8x7 are the same answer, so there are only 78 different ones. Take out the x1, x2, x5 and x10 rows, which are patterns a child can see rather than facts to memorise, and 36 are left. This printable chart colours all three layers so you can point at what is actually left to learn. MateMatty drills those 36.

The definition of "Sheldonian t-shirt", is this. I have nothing more to say than: "The best number is 73. Why? 73 is the 21st prime number. Its mirror, 37, is the 12th and its mirror, 21, is the product of multiplying 7 and 3... and in binary 73 is a palindrome, 1001001, which backwards is 1001001." — Sheldon Cooper Literally that speech is known as "Sheldon Cooper Theorem". I put the three color variations that Sheldon wore of this t-shirt. A great design for maths lovers, hope you like it!
