**A singular sensation**

To find all proven three-straight-connected numbers in a grid whose sum equals the demanded Equa.

- Choose a prefilled number grid.
- Calculate three-straight-connected numbers in any combination to satisfy the demanded Equa.
- For this game numbers are connected in straight threes vertically or horizontally only, as shown in the diagrams below.
**No “L” shape is allowed.**

- Numbers can be calculated in any combination, but keep in mind the mathematical order of operations as you calculate:

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

*Next perform all multiplications and divisions*

*Lastly, perform all additions and subtractions*

- Found straits cannot cross each other. Each number can only be used in one strait.

Find all 6 straits of Equa 16 in this 5×4 grid. The solution is as follows:

Let’s check the solution:

2 x (5 + 3) = 16

12 + 8 : 2 = 16

10 + 9 – 3 = 16

8 + 2 + 6 = 16

5 x 5 – 9 = 16

12 + 4 x 1 = 16

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.
