Move 3 matchsticks to create a figure with 5 squares

SOLUTION: Make sure you count the outer square! 🙂

Q: Represent the number 1 using the numbers 2, 3, 4, 5, 6, 7, 8 and 9 one time each.

A: 1 to the 23,456,789 power = 1!
Also 1 + (2 – 3) – (4 – 5) + (6 – 7) – (8 – 9) =
1 + -1 -(-1) + -1 -(-1)
1 – 1 + 1 – 1 + 1

The integer at the top of each of these 9 rectangles is the sum of four addends contained in each rectangle. Shade the boxes containing the addends you use to get the sum. You will use one addend in each row.
Notice that the 4 numbers circled to make -2 are not the right combination.
