Q: What does IP AMaths Notes (Upper Sec, Year 3-4): 01) Indices and Surds cover?
A: Laws of indices, rationalising surds, and exponential forms that anchor the rest of the IP Additional Mathematics syllabus.
Master the index laws so exponent and surd manipulations become automatic. Keep every expression in exact form until the last step to avoid rounding drift.

| Read time | What to take away |
| 1 second | Indices and surds are the algebra clean-up tools for the rest of AMaths. |
| 10 seconds | Rewrite powers with common bases, keep exact surd form, and rationalise only after the expression is simplified. |
| 100 seconds | Example: turn 27 and 9 into powers of 3 before solving. Then equate the indices instead of expanding everything blindly. |
