Additive inverses add to zero. the additive inverse of any number is just that number multiplied by -1. the additive inverse -1.9 is+1.9 because when you add them the result is zero
I will check for the answer on that gimme a min
The level of precision is given by the number of decimal places.
1.45 has a precision of 2 ( two decimal digits)
.0034 has a precision of 4 ( 4 decimal digits)
Numbers that end in zeros have negative precision:
100: has a precision of -2 ( 2 zeros)
15 : Whole numbers has precision 0.
From most precise to least precise:
.0034 - 1.45- 15 - 100
