uncertainty means probably, but not quite sure
All measurements have uncertainty. things that we count are usually certain
=,- Plus or minus means add or subtract the uncertain to the center number and get the range that you might have
Example I have 5 dimes in my pocket not 4 or 6
but if I have a "jar full" I might have 225 or 203 or 239 if I just make a reasonable guess
I might say I have 210 dimes +,- 20, that is $21 +,- $2 maybe I have only $18 or maybe $22
I am not sure
get the idea
