What if you had a secret math superpower that let you solve the entire 6 times table in seconds?
If you already know how to multiply by 3, you already know the answers for 6!
The Double 3 Trick
The number 6 is simply double the number 3 because 3+3=6.
Because 6 is twice as big as 3, every answer in the 6 times table is simply double the answer in the 3 times table.

How can we use this trick to solve a real multiplication problem like 6Γ4?
Solving 6 Γ 4 in Two Steps
Step 1: First, solve the easier 3s fact: 3Γ4=12.
Step 2: Now, double your answer by adding it to itself: 12+12=24. That means 6Γ4=24!
