**equations** that result in the given Equas from 13 to 24, when you calculate any three adjacent numbers in the square grid.

- You are given a prefilled grid and a list of all Equas that can be found from 13 to 24.
- There’s always at least one equation that can be made to satisfy each result.
- As a hint, you will know the total number of equations that can be found.
- Use the work area to write down all equations you find.
- In this game, adjacent numbers are three numbers connected
**vertically, horizontally or in an “****L”****shape**, as shown in the diagram below.

- Use only basic arithmetic functions: addition, subtraction, multiplication, division; and follow the order of operations when necessary

In this 2×2 grid, our task is to count Equas from 13 to 24. Also, we know that there is a total of 18 equations that can be found.

Solution:

Equa-13 (2): 6 + 3 + 4 = 13, 1 + 3 x 4 = 13

Equa-14 (1): 6 x 3 – 4 = 14

Equa-15 (2): (6 – 1) x 3 = 15, (1 + 4) x 3 = 15

Equa-16 (1): (3 + 1) x 4 = 16

Equa-17 (1): 6 x 3 – 1 = 17

Equa-18 (3): 6 x 3 : 1 = 18, 6 + 3 x 4 = 18, (4 – 1) x 6 = 18

Equa-19 (1): 1 + 6 x 3 = 19

Equa-20 (1): (6 – 1) x 4 = 20

Equa-21 (2): (6 + 1) x 3 = 21, 6 x 4 – 3 = 21

Equa-22 (1): 4 + 6 x 3 = 22

Equa-23 (1): 6 x 4 – 1 = 23

Equa-24 (2): (3 + 1) x 6 = 24, 6 x 4 : 1 = 24

As we can see, solution for this puzzle is correct.

Arithmo Basic Rules:

- To find or insert in a grid three adjacent numbers that when calculated together result in an
**Equa-X.** **Equa and Equa-X**are terms that simply mean the result of a mathematical equation. For example: 2 x 4 -1 = 7**(Equa-7)**- In Arithmo, an equation is made by connecting three adjacent numbers in a grid.
- There are five types of puzzle grid shapes: Circle, Hexagon, Rhombus, Square, Triangle. Each game has a diagram illustrating how connections should be made in its specific grid.
- Numbers are calculated together using only addition, subtraction, multiplication and division,
*with or without parenthesis.*

If a combination of arithmetic functions is used than keep in mind the following order of operations you learned in math class:

Rule 1: *First perform any calculations inside parentheses, if they exist.*

Rule 2: *Next perform all multiplications and divisions*

Rule 3: *Lastly, perform all additions and subtractions*

The order of operation rules are demonstrated in the examples shown below:

(8 – 5) x 7 = 21 (**Equa-****21**)

8 x 12 ÷ 6 = 16 (**Equa-****16**)

6 x 3 + 5 = 23 (**Equa-23**)

11 + 12 ÷ 4 = 14 (**Equa-14**)

Each Arithmo puzzle employs the basic rules, but it will also have its own set of specific rules. Please read all the rules carefully for maximum benefit and enjoyment.
