So if we want to carry out operations and get the correct sig shapes, we have to look at the limiting term, right? so if we look at what we have, we have something like 756 plus 32 .7, or sorry, 37 .2 plus .83.
00:23
If we want to add that up, that will give us something like 794 .03.
00:30
I'm going to say that's equal to 794 .03, and that is the sum of 756, 37 .2, and 0 .83.
00:44
Now, the limiting term is the 0 .83.
00:47
That's how much information we have, limiting amount of information.
00:51
And so we need to turn this number, which has 1, 2, 3, not the 0, 4 sig shapes, and turn that into having two sig figs.
01:01
And so the best way to do that would be to say 790 is our answer.
01:09
Zero would just be a placeholder, and we have two sig figs.
01:13
Now, if we wanted to multiply something, it's very similar as well.
01:17
The product of something like 0 .0032 times 356 .3 is going to be limited by the two significant digits in 0 .0032.
01:31
And so when we multiply this out, we multiply .0032 by 356 .3.
01:51
Our answer that we get is 1 .14016.
01:57
So 1 .14016.
02:00
It has 1, 2, 3, 4, 5 sig figs...
