Seven days in a week, seven colors in a rainbow... master the 7s!
Seven is just 5 + 2! You can "break apart" any 7s problem into an easy 5s problem and a simple 2s problem.
How to solve 7 x 8:
First, solve (5 x 8) = 40.
Next, solve (2 x 8) = 16.
Now, just add them together!
40 + 16 = 56
The finger trick works for 7s too! Let's try 7 x 9.
Let's solve 7 x 9
1. Touch the Fingers: Touch your '7' finger (ring finger on left) and '9' finger (index finger on right) together.
2. Count the Tens:
Count the touching fingers and all fingers below them. You have 6 fingers in this group. That's 60.

3. Multiply the Ones:
Count the fingers *above* the touching ones. You have 3 fingers on one hand and 1 on the other. Multiply them: 3 x 1 = 3.

4. Add Them Up:
Add your tens and ones together: 60 + 3 = 63. So, 7 x 9 = 63!
