Hi all!

I’ve been been stuck on this for a couple of days now and thought I’d reach out to LPTHW community.

I think I’ve worked the original formula out correctly, as they both return the same figure, but the problem I’m having is with my own formula. I used the same method to simplify my formula as I did with the example, however its outputting two different figures and I really can’t see why.

So my question is, what have I actually done wrong here and what am I not seeing?

For context I’m a carpenter that is trying to change his career, so please be gentle

Thank you in advance for your time and knowledge!

Code:

```
# Example formula.
why = add(age, subtract(height, multiply(weight, divide(iq, 2))))
what = age+height-(weight*iq/2)
print("That becomes: ", what,"Can you do it by hand?")
print("That becomes: ", why,"Can you do it by hand?")
# My formula
who = multiply(iq, add(age, subtract(weight, divide(height, 2))))
when = iq*age+(weight-height/2)
print("My formula equates: ", who, "using the same numbers as shaws.")
print("My formula equates: ", when, "using the same numbers as shaws.")
```

```
Example output:
Here is a puzzle.
DIVIDING 50.0 / 2
MULTIPLYING 180 * 25.0
SUBTRACTING 74 - 4500.0
ADDING 35 + -4426.0
That becomes: -4391.0 Can you do it by hand?
That becomes: -4391.0 Can you do it by hand?
my formulas output:
DIVIDING 74 / 2
SUBTRACTING 180 - 37.0
ADDING 35 + 143.0
MULTIPLYING 50.0 * 178.0
My formula equates: 8900.0 using the same numbers as shaws.
My formula equates: 1893.0 using the same numbers as shaws
