Horse is 10
Boot is 1
Horseshoe is 2

BODMAS 10 X 2 + 1

Here we go can people post not just the answer but what they think the values are
#11
Horse is 10, the horse shoe is 2, boot is 1. so horseshoe times horse is 20 +1 is 21

Horse is 10
Boot is 1

correct but look again
#13
only way you xan really get mixed up is if u dont account for the two horsehoes

Ah that makes more sense. Wish I'd saved myself two pieces of A5 and a lot of confusion and realised that sooner. :{

any brackets then multiplication & division then addition & subtraction

so if horse=10, horseshoe=4, boot=2 its 10×4=40+2=42

no?

...and a lot you don't :(X)

Maths wasn't my strongest subject, in fact I'd go so far as to say it was my weakest X) I used to ask the question to my maths teacher 'when would I ever need algebra and all the complicated maths fractions etc'?...he never did say, 'well, a question may come up on HUKD one day...and you may need to know the answer' :(X)

Same question was posed to my Chemistry and Physics teachers as well...I was a lovely student :)X)

The answer is 21..consider each symbol to be a variable and then we can see that we've got three linear equations with 3 variables therefore the value of each variable can be found. Suppose the horse is x, the pair of horseshoes is y and the pair of heels/boots (I'm not sure) is z..look at the first equation 3x = 30 so x= 10.. now look at the 2nd equation x + 2y = 18 now put x = 10 then you'll get y = 4.. look at the 3rd equation which is y - z = 2.. put y = 4 which will give you z = 2. Now let's look at the question which is z/2 + x(y/2) = ?? Putting the values of x,y & z we get 2/2 + 10*(4/2) = 21
#39
1 Horse + 1 Horse + 1 Horse = 30
3 Horses = 30
1 Horse = 10

1 Horse + 2 Horseshoes + 2 Horseshoes = 18

18 - 1 Horse = 4 Horseshoes
18 - 10 = 4 Horseshoes
8 = 4 Horseshoes
2 = 1 Horseshoe

2 Horseshoes - 2 Boots = 2
4 - 2 Boots = 2
4 - 2 = 2 Boots
2 = 2 Boots
1 = 1 Boot

1 Boot + 1 Horse x 1 Horseshoe = ?

Here is where observance to BODMAS will give different answers.

a) (1 Boot + 1 Horse) x 1 Horseshoe = (1 + 10) x 2 = 22
or
b) 1 Boot + (1 Horse x 1 Horseshoe) = 1 + (10 x 2) = 21 <- This is my answer
