To insert the set of given numbers into the empty squares so when they are calculated in adjacent threes they equal the demands in the shaded boxes.
*Crossroads game differs from CrossMath in that the squares don’t dictate the math operation that needs to be performed to solve the puzzle. In Crossroads, you are challenged to perform the order of operations on your own.
Insert numbers 1, 3, 4, 6, 7 and 8 in this CM8 shape which initially have two numbers (2 and 8) so all horizontal and vertical calculations are correct and satisfy the demands in the black squares. The solution is as follows:
Let’s check the solution:
7 x (6 – 2) = 21
8 x 3 -1 = 23
2 x (1 + 8) = 18
8 x (7 – 4) = 24
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.
