If you added 432.2 + 24.04 how many significant figures would it be?

Question

would it be five in the end result?

Answer 1

Answer is 4.

You always go with the lowest significant figure.

So adding the 2 numbers will equal 456.2.

Reason being is that the "fifth" figure for 432.2 is unknown, so it wouldn't be accurate/reliable to use 5 figures in the end.

It also would depend on what level math your were doing.  For elementary math, you'll use 5 figures because they'll be focused on teaching you addition.  However, for more advanced math where they teach the significance of "significant numbers", it'll be 4.  If you're in college and writing down numbers, particularly for measurements in labs, you better use the proper significant numbers or you'll get points knocked off.

Answer 2

NO, you do sig figs for addition by the least number of decimal points

so your result would have 3 in front of the decimal and 1 after.

4 sig figs

Answer 3

Yes five would be the end result because 432.2+24.04=456.24 and significant figures are any figures that actually mean something.

(EX:0.20 would only have one significant figure because the other numbers are only place holders and have no meaning or significance to the actual answer.)
