You made this so easy, thanks 😍😍

[@yushna_1785]

ok, I have 1 doubt. Here in 8:34 why don't we just minus both the upper bound values?

[@RAGEFROST_69-]

Because the subtraction rule of the upper bound and lower bound is different

[@RAGEFROST_69-]

Nice explanation, I really understood the concept . ❤

[@AceMaths]

In Exam style question 2 Part C they asked for the upper bound And you calculated the lower bound So is this the formula to calculate the opposite? Or you did a mistake

[@AceMaths]

The terminology in part c) could be seen to be rather confusing. What we are trying to find is the 'upper bound' or 'maximum' DIFFERENCE in the weights. For this difference in their weights to be maximised, I took the upper bound of Anu's weight and subtracted the lower bound of Zoe's weight.

[@ru.tv1studios]

@@AceMaths I got it👍🏼

[@AceMaths]

Excellent!

[@jaeleighdesousa7918]

Can you do harder questions on this topic?

[@SerenicRoam]

sf and decimal places please my exam is tomorrow

[@Alex-nf9gj]

hi what happens if it asks to the nearest whole number?? what do we divide with?

[@yushna_1785]

divide with 2 either way. All values should be halved and you get that by dividing it with 2.

[@maramalamir2166]

Thanks

[@AceMaths]

You’re welcome!! 😊😊😊

[@Fara7hh]

thank uu

[@AceMaths]

You’re very welcome!! 😊

[@RawanAlmedhaweb]

the second question is nit a significant figure because its a trailing 0 and we know that trailing 0s don't count as significant figures

[@RawanAlmedhaweb]

unless it had a decimal point but even if then there would be 3 sf
