Another Math problem(31 posts)
back to the original question - if the objective is an easier way to mentally calculate this particular problem you can try
46/4 = 11.5 *100 = 1150
this takes advantage of the fact that 25 is 1/4 of 100.
And Scott, I didn't know you had just had surgery - didn't mean to make light of the need for meds.
Grandson was saying at school they tell him to break down into 10's..
Hence my original of OK 40x20 and then the 6x5 Theory.... so whilst I see the explanation. I still Cannot explain WHY the 40x20 etc does not add up...
My old grey matter not so quick these days, Like Ted says there are easier ways and conundrums,
Probably best to stay with the young of today 'Do NOT ASK, just use the calculator Ha!!!!!!'
Kate I help out with reading & math each week at my local primary school. The way they teach them to multiply baffles me. Then there are number lines etc.
I still think my generation were taught the best way. IE the forties & fifties in my case.
Scott I also did not know about your op so I wish you well for a good recovery. Sounds complicated. I also suffer with my neck having sudden spells of dizziness and occasional episodes where I almost black out. This all due to a problem in the neck pressing on the blood flow. Sadly they refuse to carry out an op as considered too dangerous so I live with it.
