66 tens = 660

18 ones(More correctly ; UNITS) = 18

9 hundredths = 0,09

Adding

660 + 18 + 0.09 = 678.09

NB The numbers of number columns are , from the decimAL POINT to the left;-

UNITS(1), TENS(10), HUNDREDS(100), THOUSANDS,(1,000) TENS of THOUSANDS(10,000), HUNDREDS of THOUSANDS(100,000), MILLIONS(1,000,000).

From the Decimal point to the right:-

TENTHS(0.1) , HUNDREDTHS(0,01), THOUSANDTHS(0.001), TENS OF THOUSANDTHS(0.0001), HUNDREDS OF THOUSANDTHS(0.00001), MILLIONTHS (0.000001)
