I had to go around town picking up numbers from various places so he can work out some sort of total for something or other. This I have done and it's all I'm expected to do.
I'd like to surprise him by pretending I've also worked out the arithmetic but as I think I've mentioned before , I'm no good at this type of thing. Anyway here's the arithmetic.
((1+4)(6+3)). ((4+1+1)(8+1)((4+5)-9))
also ((5-3)(7-1)). ((9-5)(8-1)(7-3))
I was never taught maths in my day using (bidmas?) method although I'm getting used to it, slightly but the double brackets I still struggle with.
This is all dependant on me picking the correct numbers up in the first place of course.
Of course I will come clean about working out the numbers. He'll know anyway!

Assuming that you got the numbers right and then wrote it down correctly and that a couple of glasses of Shiraz didn't addle me. In my head I get.
45, 54, 0. 24,112.
5x9=45. 6x9x0=0. 2x6=12. 4x7x4=112.
((1+4)(6+3)) = 45
( (4+1+1)(8+1) ((4+5)-9) ) = (6x9) x (9-9) = 54 x 0 = 0
((5-3)(7-1)) = 12
((9-5)(8-1)(7-3)) 4 x 7 x 4 = 112

assuming you wrote it correct and I understood what you meant!

Haha I did the 4th one twice in my head. Like I said as long as a couple of....

Encouraging your Grandson to do the maths is a gift he will always appreciate and remember you for.
Question Author
Thanks all. I'll amaze him with my genius (not)!
Togo, it seems more like he's teaching me, but yes I know what you mean.
Again, thanks all.
BTW it's BODMAS but here you only have brackets and otherwise equivalent operations so you just do the brackets inside out so for example:
((4+1+1)(8+1)((4+5)-9))
((6)x(9) x ((9)-9))
6x9x0....
These assume its 4 seperate calculations and the dot between them dont mean something (I vaguely remeber a.b (adotb) at night school but forgot what it means)
"." can mean multiply, in which case ...

> ((1+4)(6+3)). ((4+1+1)(8+1)((4+5)-9))

(5x9)x(6x9x0) =
45x0 =
0

> also ((5-3)(7-1)). ((9-5)(8-1)(7-3))

(2x6)x(4x7x4) =
12x112 =
1344
the . means multiply normally but I took it to be punctuation in this case or I would have expected it here for example...
((1+4).(6+3))
Having received the numbers from you, has he worked out the arithmetic himself ?
well the dot wouldnt be needed in your example.
The only reason I thought it might be two questions not 4 is the way imlostagain used the word ALSO and didn't put each on a seperate line
Question Author
Sorry I've just returned home. The dot is indeed a punctuation mark and there are four seperate calculations. I should have made that clear. Apologies for any confusion.
Thanks for the update...Good luck.
It's defo called BIDMAS now not BODmAs like it was when we was at school TTT....helped my neice with it a few times. ... I found its I for indeces (powers) not order or other anymore. Same answers tho
My goodness, absolutely no idea, another language. I admire those that understand and honour those that can get the right answer!
From my memory of BIDMAS/BODMAS theres unnecessary brackets in them questions, eg
((1+4)(6+3)) could just be (1+4)(6+3)

((4+1+1)(8+1)((4+5)-9)) could just be (4+1+1)(8+1)(4+5-9)
