Watching this before tomorrows exam 😭😭

[xsiax_]

revising for my gcse's, and this was very helpful, thanks!

[kaed]

I can’t describe how helpful this was since i barely knew anything about LB and UB before watching this clip.Keep going❤❤

[global_overmatters]

You are the best, honestly. I’m so glad I stumbled upon your videos, thank you sm for the free revision resources❤

[materialgirly]

This was so helpful! I used to always struggle with bounds but now understand it thanks to this!

[kikiboo-]

[belugacat]

You’re the best mate💯💯 thank you for such useful video👍

[ammarahsurve]

Thank uu! I was so confused with this and know i understand

[Fader-kfis]

Hey @ 1st class math- can u please make a video of rules, about nearest decimal place nearest sf and how to find the upper bound nearest with them

[TheMathLab]

I was confused about the maximum area, because your are unable to use 25cm since that inequality doesn't have a line through it?

[mariahussain]

Your videos are so helpful. I have a question, why did you multiply 25 with 8.5 for the maximum possibility whereas we know that length's upper bound is less than 24 and widths upper bound is less than 8.5? Please help!

thanks for explaining this mate ya helped me a ton

Why r there missing topics on the checklist for edexcel higher on your website like pythagoras

[samuellacobbinah]

The practice questions on your website why is it that with money bounds u use lets say 8.49 instead of 8.5 and 1.64 instead of 1.65 for maximum total amount of money?

I cant believe im in y11 it doesnt feel real…
