think of the # 2 as 2.00000000000 the closer that the number after the decimal point...gets toward the whole number (2) makes the number bigger.. if that makes sense I.E. from largest to smallest.... 2.3 , 2.03 , 2.003 , 2.0003 the number after the decimal point goes from tenths to hundreths to thousandths ....i hope this helps! think of it like money.... 2.30 is 2 dollars and 30 cents. 2.03 is 2 dollars and three cents
