Just wanted to say thanks for CARRYING my IGCSE November A* last year!!! Easy 93%

[@GingerMathematician]

Like how 93% was easy :-)

[@aunshah3836]

How do you actually know your percentage from mocks or something? Because I only know my grade not even percentile is mentioned anywhere on my IGCSEs giving in Pakistan btw.

[@SmartGuy222]

Mr. Ginger, could you please post the following topics:
1. Money
2. Interest
3. Percentages
4. Rate and Ratio
5. Measurement
6. Speed-Time and Distance-Time graphs

thank you so much for this!! was extremely confused with this topic as a whole and this video single-handedly cleared all my doubts:)

[@GingerMathematician]

Great I could help 🙂 Do you have mocks soon?

[@user-ob1yl6so6v]

i swear this topic is harder and more confusing than whole igcse syllabus. after the day i studied this topic, i forgot almost everything. also roundings are similarly hard for me. i know it looks actually pretty easy and for most of the people it is easiest but for me, it's exactly not. i hope i won't miss a* just because of these type of question because it's sooo confusing (btw my teacher said that i always make mistakes in supereasy questipns especially first questions of ig are generally so easy. but peraonally, i think that studying harder questions instead of basic stuff makes more sense. but i lose marks just because of basic things and this makes me soo sad.

[@GingerMathematician]

Practice makes the silly mistakes disappear 😊

[@slaveofAllah14]

Mr ginger, do you have a video related to speed time graphs? I didn’t seem to find one in your channel…

[@GingerMathematician]

Not quite yet... it's coming!

[@rainb1750]

Sir what if a value is to the nearest significant figure like 2 how do we approach it .I understand that
1 decimal places=0.1 so 1 significant figure will equal what?

[@GingerMathematician]

If a value is given to the nearest significant figure, it means that only one digit is certain and the other digits are uncertain. For example, if a value is given to one significant figure, it means that only the first digit is certain and the other digits are uncertain.
In terms of decimal places, one significant figure is equivalent to one decimal place. So if a value is given to one significant figure, it means that it is accurate to one decimal place.
To answer your question specifically, if a value is given to the nearest significant figure of 2, it means that it is accurate to one digit after the decimal point or to the nearest 0.01. This is equivalent to two decimal places.

[@tankyplayz1738]

At 12:40 of the video u could have extended it till 14.5 of the 14 as the highest common factor and so of the other numbers

[@GingerMathematician]

We do not take the upper bound of the factor itself, we take the upper bound of the formula :-)

[@shinninglightministry7050]

Now we're talking

[@GingerMathematician]

All the good stuff :-)

[@the_aesthetic_girl_1]

A quick question, as the amount of people at the footbal match is discrete data, wouldn't you have to take away one from the upper bound? This is what I was taught, so I am just asking whether you must do this or not. Thank you

[@GingerMathematician]

Depends on the question

[@AliaAliaa-dv7fn]

Outstanding video sir ❤, I’ve been watching your videos for quite a while and I must say that I am really great full I stumbled across your explanation. I also have a question in 6:08 why did you halve the 0.5 and 10? That would be wonderful if I got an answer and if there is a better way for communication please tell me!
