Where your math skills are waiting to be unleashed
Object of the Game
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.
How to Play
- Choose a prefilled number grid.
- Equa demands are prefilled in the shaded boxes.
- Insert the numbers from the given set into the empty squares so each adjacent three numbers when calculated together satisfy the Equa demands for both the row and column.
- 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
- For this game, adjacent numbers are three numbers connected horizontally or vertically, as shown in the diagrams below. No “L” shape connection is allowed.
- Use only basic arithmetic functions: addition, subtraction, multiplication, division; and follow the order of operations when necessary.
- In some large size grids of Crossroads, you will have Equas on both the left and ride side of the puzzle to solve
*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
