Trap 1: Assuming Division Always Comes Before Multiplication

The most persistent division misconception: because D comes before M in BEDMAS, division must always be evaluated before multiplication. This is wrong. Division and multiplication have identical precedence — when both appear in an expression without brackets, you work strictly left to right, whichever operation appears first. In 6 ÷ 3 × 2, you evaluate left to right: 6 ÷ 3 = 2, then 2 × 2 = 4. The answer is 4, not 1. If it were 1, you would need to write 6 ÷ (3 × 2).

Trap 2: Placing Equations That Produce Non-Integer Results

In BEDMAS the game, all valid equations must produce whole number (integer) answers. This constraint applies to every step of the calculation, not just the final result. An equation like 7 ÷ 2 + 3 = ? is invalid because 7 ÷ 2 = 3.5, which is not an integer. Before placing any equation involving division, verify that the division produces a clean integer result. This check needs to happen at every division step in a chained equation, not just at the end.

Trap 3: Division in Chains Without Checking Each Step

When building chains, division constraints cascade through every part of the chain. If your chain includes 18 ÷ 3 = 6, the value 6 must then produce valid integer results in every subsequent part of the chain that uses it. The most reliable approach when planning a chain with division: work backwards from the valid endpoint you want to reach, not forwards from the tiles in your rack. Decide what answer you need, then find combinations of tiles that produce it through valid integer arithmetic at every step.

How to Avoid These Traps in Play

Build a quick mental checklist: (1) Is there both × and ÷ in this equation? If yes, work strictly left to right, not D before M. (2) Does every ÷ in this equation produce a clean integer? If not, the equation is invalid — do not place it. (3) If this is a chain, have I verified integer results at every step? With practice, this checklist becomes automatic and takes under three seconds per equation.
