I want to multiply 46x 25 ok so it equals Total 1150.

Now to make it easier for mental working..
Multiply 40 x 20 = 800
6 x 5 = 30 ... Total 830.

Can someone explain why the difference in answers...I am going round in circles :)

It's a case of cross multiplication as in

46*25 =

(40+6)*(20+5) =

(40*20)+(40*5)+(6*20)+(6*5) this is the cross multiplication (had to dredge this up from long. long, long ago).

It may be the meds talking, I defer to Moree.

Math is tertiary to neck surgery :)

That is how I felt, like a sad giraffe.
A sad giraffe with math problem is worse though.

Do they call a sad Math Giraffe An Algebrath.

Kate if I were working that out in my head it would be,

40 X 25 = 1000
6 X 25 = 150

Interesting conundrum though so hats off to moreeg for providing the answer and to stop you feeling Cross :)

Hey!!! Scott... Good to see you posting with your usual sense of humour, not easy after your Op last week end..

Hello kate and thank you again for all your well wishes these last few weeks.
The bad meds are being tapered, won't be using them much longer.

Having had to be re-admitted for post-op issues was no fun indeed.
I think we're done for overnight stays, at least we better be.
