To find all proven three-straight-connected numbers in a grid each of whose sum will equal one of the demanded Equas.
Find 6 straits of Equas 14, 16, 17, 18, 19 and 22 in this 5×4 grid. The solution is as follows:
Let’s check the solution:
2 x 11 – 3 = 19
4 + 6 + 4 = 14
8 x (10 – 8) = 16
3 x 7 + 1 = 22
11 + 8 – 1 = 18
3 x 7 – 4 = 17

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.
