Clear working is one step per line, in order, with the operation noted beside each step. That is true whether you write on paper, type on a keyboard or use a tablet.
This page shows three ways to share working without special equipment. The online-lesson readiness check can help you test which one your device supports.
Why does working matter in an online lesson?
A teacher cannot see your thinking unless it is written down. If only the final answer arrives, the teacher has to guess where a mistake started, and that is slower for both of you.
Good working also helps you. A line-by-line solution lets you see your own error before anyone else does.
Three ways to show working
Paper and camera. Write on paper, hold it to the camera or take a photo, and send it to the teacher. It needs good light and large handwriting.
Typed steps. Type each line on its own row, using plain symbols such as x², √, ×, ÷, ≤ and brackets. It is clear for algebra and arithmetic, but slow for graphs and diagrams.
Tablet or stylus. If you have one, it feels closest to paper. It is not required, and you can get the same benefit without it.
For any method, agree with the teacher beforehand which way they can read easily.
Worked example
Here is a typed solution to: solve 5x − 3 = 2(x + 6).
5x − 3 = 2(x + 6)
5x − 3 = 2x + 12 expand the bracket
5x − 2x = 12 + 3 collect x terms on the left, numbers on the right
3x = 15
x = 5 divide both sides by 3
Check: 5(5) − 3 = 22 and 2(5 + 6) = 22Each line is one step, and the note on the right says what was done. The check at the end proves the answer.
Notice that nothing is squeezed onto a single line. A teacher reading this can point to exactly one line and say “this step needs another look”.
The mistake to watch for
The most common typing mistake is ambiguity. A student types x+3/2 meaning “(x + 3) divided by 2”.
A reader will see x + 3/2, which is x plus one and a half. The working is then marked against a different expression from the one you meant.
The correction is to put brackets round the numerator of any fraction that has more than one term: (x + 3)/2. Another mistake is typing only the answer, which hides the step where an error would have shown.
Check yourself
1. How should you type “x plus 3, all over 2” so it cannot be misread?
Show answer
(x + 3)/2. The brackets show that the whole numerator is divided by 2.
2. Type the solution of 4(x − 1) = x + 8 in steps, with a check.
Show answer
4(x − 1) = x + 8
4x − 4 = x + 8
4x − x = 8 + 4
3x = 12
x = 4
Check: 4(4 − 1) = 12 and 4 + 8 = 123. Why is one step per line better than writing everything in one row?
Show answer
A teacher can point to the exact line where something went wrong. On a single row, errors hide and the reader has to rebuild your steps.
Where this leads next
Next, check audio and privacy before a call so the lesson is easy to hear as well as easy to see. If you are returning after a gap, keep a return-to-study plan manageable is a good companion.
If you are unsure which method suits your device and your handwriting, online one-to-one Mathematics tuition gives a teacher the chance to see your working live. The paid one-hour trial starts from RM80 at the assigned teacher’s confirmed rate, and any ongoing arrangement is agreed directly with the teacher afterwards.
