How we got there
Read this like a teacher at the board. We go slowly, name every number, and say why we take each step.

1. What is the question asking?
Read the question twice. Circle the unknown. Underline every number and unit. The paper is asking: Phepha 3 tsalwa ra ntirho, Giredi 10. Papila ra xinghana eka xaka hi ntlangu. Ku leha marito ya kwalomu ka 180 ku ya eka 200, hilaha phepha ri lerisaka hakona.
In other words — as if you have never seen this before
If you have never seen this before: Timaraka ta xivumbeko ta lahleka loko adirese kumbe ku hetisa ku nga ri kona. We will name a method in words, write the formula with no numbers, then substitute one line at a time.
2. What do we already know?
Papila ra xinghana. Adirese, siku, xinkhenso, miri, ku hetisa, vito.
3. Which method — and why this one?
Timaraka ta xivumbeko ta lahleka loko adirese kumbe ku hetisa ku nga ri kona.
4. Step-by-step working
01 / 06
Nhla
Adirese ya wena na siku eka tlhelo ra xinene. Xinkhenso: Xaka ra mina …
adirese na sikuWhy this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.
02 / 06
Tirhisa nawu
Tindzimana timbirhi to koma ta mahungu. Ku hetisa: Hi mina xaka ra wena, kutani vito ra wena.
ku hetisa ka xinghanaWhy this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.
03 / 06
Kambela
Ririmi ri nga ntshunxeka, kambe xivumbeko xa tshama.
timaraka ta xivumbekoWhy this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.

Step G — Sense-check the size
Ask: is this the kind of number a Grade 10–12 paper would want? A speed of 3 000 ms for a learner walking, or a probability bigger than 1, means a unit or algebra slip. Estimate first: round the numbers and do the sum in your head.
Why this step: Markers write ‘unrealistic’ in the margin when the method is right but the size is wild. A 10-second head check often finds a missing 10² or a unit that never changed.
05 / 06
Step F — Box the answer with its unit
Adirese, siku, xinkhenso, tindzimana timbirhi, ku hetisa ka xinghana na vito.
Why this step: A number without a unit is half a mark on a Physics paper, and a marker can miss a Maths answer that is buried in working.
06 / 06
Step H — What the marker is looking for
On an NSC memo you usually earn: (1) a method mark for naming the right formula or idea in words, (2) an accuracy mark for substituting the given numbers with units, (3) an accuracy mark for the boxed answer with its unit. Write those three lines even if you are unsure of the arithmetic — blank pages score zero.
Why this step: First-timers chase the final number and leave the method blank. The memo still pays out for the idea and the substitution even when the last line is wrong.
5. The answer
Adirese, siku, xinkhenso, tindzimana timbirhi, ku hetisa ka xinghana na vito.
6. Check it like a marker
Ku hetisa ka ximfumo eka papila ra xinghana ku lahlekeriwa hi maraka ya rejisitara.
7. A trap first-timers fall into
First-timers often grab the first formula they remember, mix units (cm with m, minutes with seconds), or drop a minus sign. Write the formula in words first: “this equals that, because…”
