Пронађите и пребројте све Екве од 13 до 24, када рачунате било која три суседна броја у квадратној мрежи.
У овој мрежи 2×2, наш задатак је да избројимо једначине од 13 до 24. Такође, знамо да постоји укупно 18 једначина које се могу пронаћи.
Решење:
Еква-13 (2): 6 + 3 + 4 = 13, 1 + 3 x 4 = 13
Еква-14 (1): 6 x 3 – 4 = 14
Еква-15 (2): (6 – 1) x 3 = 15, (1 + 4) x 3 = 15
Еква-16 (1): (3 + 1) x 4 = 16
Еква-17 (1): 6 x 3 – 1 = 17
Еква-18 (3): 6 x 3 : 1 = 18, 6 + 3 x 4 = 18, (4 – 1) x 6 = 18
Еква-19 (1): 1 + 6 x 3 = 19
Еква-20 (1): (6 – 1) x 4 = 20
Еква-21 (2): (6 + 1) x 3 = 21, 6 x 4 – 3 = 21
Еква-22 (1): 4 + 6 x 3 = 22
Еква-23 (1): 6 x 4 – 1 = 23
Еква-24 (2): (3 + 1) x 6 = 24, 6 x 4 : 1 = 24
Као што видимо, решење за ову слагалицу је тачно.
Основна правила Аритма:
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.
