In the third line, it’s a tire plus two shock absorbers plus two shock absorbers; so, one shock absorber equals 1.

How do you know that one shock absorber equals 1? Perhaps it equals 6.

15 — only one spark plug in the final line.

Shock absorber…. but yes there’s only one and 15 is correct.

There IS only one; but that is a multiplication operation there…

5+2×10
5+(2×10) = 5+20 (because you do multiplication before addition)
so the answer is 25

There is only one shock absorber, so
5+(1×10)=15

the Shock Absorber is “2”
because —> 5+2+2=9

A pair of shock absorbers (as shown in that line) is 2. So a single one (as in the final line) is 1. 15.

5 (tire) + 1 (shock) = 6
6 x 10 (valve/lifter) = 60
so isn’t the answer 60?

why is this not:

5 + 2 x 10 = 70

there are no brackets

thanks

(5+1) x 10 = 60

5 + 1 X 10 = 60
No parentheses, so operations are calculated sequentially left to right.

Nope. Mathematical hierarchy says that multiplication comes before addition even in the absence of grouping symbols.

Please Excuse My Dear Aunt Sally?

Oops! Sorry Kieth, didn’t see you already mentioned this.

The problem I have is the assumption that a single shock absorber equates to one. Just because the image of two shocks equals 2 doesn’t necessarily mean that the single is 1. So basically the last line is an algebraic expression: 5+X*10 = Z

I’m with you on this one. The middle image in the last line is undefined. There is no solution.

The key is the order of operations on step 4. Many people forget that.

Ron – the key issue is that while S = 2, half of S = 1
In line #3, there are 2 of S, but in line 4, there is only 1
Therefore, #4: T + 1/2S x P = X T+(1/2SxP)=X T+(1/2 2 x 10) = X
5+(1×10)=X 5+10= 15

Yup. You are correct. I didn’t notice that there was only 1 shock absorber. Thank you.

There are a lot of opinions, but does anyone know the actual CORRECT answer?

The order of operations is remembered by the Acronym PEMDAS.

P –> Parentheses first
E –> Exponents (ie Powers and Square Roots, etc.)
MD –> Multiplication and Division (left-to-right)
AS –> Addition and Subtraction (left-to-right)

If you remember Algebra you know this.

So the operations are performed as follows.
1X10 = 10+5 = 15

Cool method…. but how do I remember the acronym?

Please Excuse My Dear Aunt Sue

the answer is 15…. get a brian moran!

LOL @ moran

After seeing the comments, faith in human intelligence is utterly destroyed.
And yes, it is 15.

You can’t assume that a single shock absorber is 1. Two shock absorbers together equals 2 so it is also possible, in fact maybe even likely, that one shock absorber is the square root of two if we assume that two symbols next to each other with no operation sign separating them means they are multiplied as in 2x = 2 times x. If one shock absorber is x, and absorber absorber is xx = 2 then x = square root of 2 = 1.4142 etc

Math Answer = 25

60, I believe.

5 + 1 x 10

5 + (2 x 10) = 25

It’s 15.

5 + (1 x 10) = 15

In the third line, it’s a tire plus two shock absorbers plus two shock absorbers; so, one shock absorber equals 1.

I’m totally stuck. I keep coming back to this…

This is so easy. the answer is 17.

Proof:

#1 3P=30, P=10

#2 P+2T=20, 10+2T=20, 10-10+2T=20-10, 2T=10, T=5

#3 T+2S = 9, 5+2S=9, 5-5+2S=9-5, 2S=4, S=2

#4 T+S+P=X, 5+2+10=X, 17=X

Doh! I didn’t notice the different operand on #4.

the answer is 25.

Proof:

#1 3P=30, P=10

#2 P+2T=20, 10+2T=20, 10-10+2T=20-10, 2T=10, T=5

#3 T+2S = 9, 5+2S=9, 5-5+2S=9-5, 2S=4, S=2

#4 T+S x P=X, T+(SxP)=X, 5+(2×10)=X, 5+20=X, 25=X

The key is the order of operations on step 4. Many people forget that.

Ron – the key issue is that while S = 2, half of S = 1

Therefore, #4: T + 1/2S x P = X T+(1/2SxP)=X T+(1/2 2 x 10) = X

5+(1×10)=X 5+10= 15

Yup. You are correct. I didn’t notice that there was only 1 shock absorber. Thank you.
