We know that the digits of a number, one by one in order from left to right decrease in value rapidly. Let us illustrate it by examples. Mass of a gold ornament is 23.473 g. Round off to (i) two decimal places, (ii) one decimal place. 23.473 g = (2 x 10) + (3 x 1) + The successi..

This Tutor Vista is GREAT! loved this session, it helped me heaps.
I think the tutors knew their stuff really well and was very helpful. math was actually something I dread.not anymore ,Thank you Tutor Vista - jennifer,New york
Tutor Vista tutors actually helped me to think through some of the problems instead of just doing them for me.Now i am more confident with math ,Thank you all
You are an amazing tutor. So knowlegeable and patient. Very clear in explanations, 2 thumbs up -kelly
