I used to know how to do this but I havent donethis for over a year and forget most of it.
I have looked at websites (like :Trial & Improvement n Maths Online)
and book ( book just confused me cos the example) but I dont know fully cos Im stressed and confused n a I get feeling that its gonna be on the calculator paper tommorrow
On Trial & Improvement site Trial & Improvement
The part I didnt understand the end part of the first example ..........
On the "Maths Online" Maths Onlineeverything made sense to me until I read :
"7.3 + 2.7 = 10, 7.3 x 2.7 = 19.71 too small, but pretty close.. not close enough ? !" I dont know why it isnt good enough.
Please help someone I really need to pass that exam
