There's been some news lately about the discovery of three cubes that sum to 42. Namely, Andrew Sutherland and Andrew Booker discovered that (-80538738812075974)^3 + 80435758145817515^3 + 12602123297335631^3=42
(<https://math.mit.edu/~drew/>) 

I was tinkering with this a bit, and I'm not getting 42 in R. 

I do get it in other places (WolframAlpha), but R gives me this:

```
> (-80538738812075974)^3 + 80435758145817515^3 + 12602123297335631^3
[1] 1.992544e+35

```

Any idea what I'm doing wrong? Is it a limitation with large numbers in R? Or am I (very probably) just doing something dumb?
