About Comparing Decimals. ComparisonSymbol 0.7 vs. 0.70= 1.90 vs. 1.09> 2.789 vs. 7.289< 100.00 vs. 99.999> 758,909.4 vs. 758,909.385> 12.12 vs. 12.120= 134,343,567.789 vs. 1.93> Symbol Key less than = equal to
About Adding and Subtracting Decimals When Subtracting decimals, make sure that the numerals have the same amount of digits. For example, if I wanted to subtract 2.67 from 3.7 I would have to “add” a zer0 to the end of 3.7. Even though there are more numerals doesn’t mean that the value changed. 3.7 = 3.70 It’s just a way of saying there is none of the place value(s). When Adding decimals, you should also “add” zeros. Remember there is no special way to add and subtract decimals. (Use the traditional adding and subtracting method. 3.70 3.70 -2.67+2.67 1.03 6.37
