maths with Ron again
we did mass (kg, g) -- 1kg = 1000g

had to do addition and subtraction e.g. 4kg 9g - 2kg 55g

realised that it was easier for Ron to convert all to grams before calculating e.g. 4009-2055
then convert all back to kg and g

or else he would easily forget the zeroes and do like 409-255 especially when the g does not consist of 3digits

there was carelessness on Ron's part too when he forget the zeroes behind when writing in grams -- had to do corrections cos he simply tikam and anyhow break down the digits into kg and g e.g. 4972 = 49kg 72g cause it looks even that way, when its actually 4kg 972g

reminded Ron regarding the steps to tackle mass problems before going off

#1 convert kg and g into g -- if g is only 1digit/2digits, add 2/1zero(es) in front to make the g consist of 3digits, e.g. 057g
#2 solve as per normal
#3 last 3 digits = grams, the rest falls under kg
