Have had it for a couple of weeks and it's been really helpful in simplifying equations so I can break them down and understand them better, i recommend, so yeah just use it if you forget something, the reason why I put 5 stars is beacuse it was INCREDIBLE I can't believe it don't have 5 stars it's that amazing, it helps out so much but what I do would like is for a guide how to use it before rushing and not having that.

Upper bound = \(32 + 0.5 = 32.5~\text{cm}\) Lower bound = \(32 - 0.5 = 31.5~\text{cm}\) 140 cm, measured to the nearest 10 cm: The degree of accuracy is nearest 10 cm.
Add 1.96 times this number to your mean value to find the upper bound. So, if the mean is in cell D1 and the last result is in cell D4, type “=D1+ (1.96D4)” into a blank cell to get
Work out the lower and upper bounds of the suitcase. Since the number is rounded to the nearest 10 the scale that the bag is weighed on is increasing by 10. So the lower bound is halfway between 20 and 30
