First, understand the question, not the answer
Most "I am stuck" moments are really "I have not fully read the question" moments. Before trying to solve anything, put the problem in your own words. What is it giving you? What is it actually asking for? Underline the numbers and conditions. A surprising number of problems unlock the instant you say clearly what they want.
Shrink the problem
If the problem is too big to see, make it smaller. Try an easier version: smaller numbers, one variable instead of three, the first case instead of the general one. Solving the tiny version often reveals the method you then scale back up.
- Replace hard numbers with small, friendly ones and solve that first.
- Draw it. A diagram, a table, or a quick sketch offloads the problem from your head.
- Ask what topic this is testing, which points you at the tool you are meant to use.
Use a hint, not the answer
When you are truly stuck, the worst move is to read the full solution. You get the dopamine of "oh, of course" and learn almost nothing, and the next similar question will stop you just as cold. What you want is the smallest possible hint: the next single step, not the whole path.
After you solve it, look back
Once it clicks, do not move on immediately. Ask: what was the key step I was missing? Could I spot that trigger next time? This thirty-second review is what turns one solved problem into a pattern you recognise across many future problems.
