40 + 40 x 0 + 1 =

A- 1
B- 41
c- 0

I say its B-41 as you need to multiply then add. (from what i remember of standard grade maths the acroymym BOMDAS- brackets off, multiply, divide, add, subtract)

DH says its 1.

please tell he's wrong!

a.

bodmas

It's 1 I think - 80 lots of nothing is nothing, plus 1 is 1

B - BODMAS rules!!

41.

40 + 0 + 1

A - 1

you are right it is 41 if it was (40+40) x 0 +1 it would = 1

muliply then add. so x 0 = 0 +1 = 1

I think it's 41. The multiplication needs to be done first.

1.

or should it have brackets for that bit...??? (40x0) if not then 1.

1

B no brackets/of or divide so multiply first then then add.

Answer is a. 80x0 is 0 then add the 1.

It's B

B also.

Bodmas- but the itsjustafleshwound way, not the atyourcervix way!!

uthere are no brackets so the x comes first,

I don't see how either can be right as there are no brackets, so it is unclear whether you are adding 40 + 40 (ie 80) and then multiplying that by 0, ie giving you 0 + 1, or whether you are multiplying 40 by 0, to give 0, adding that to the first 40 and then adding 1.

I'd go for 41 as well.

41
(because BODMAS applies unless specified otherwise).

I would have said 1 as well. Have seen things like this and don't know what BODMAS is. Clearly my school was lacking in mathematics teaching!

it's 1 definitely.......I think anyway....

Ds says that's a nasty question as it depends on the format. Some people use PEMDAS, which is parenthesis, exponents, multiply, divide, add. Or, there's BIDMAS, which is brackets, indices, divide, multiply, add.

(I've no idea what he's talking about) I'd say it was 1.

It's a spankingly bad question btw.

What age group is it aimed at?
