7 + 0.9 + .03 = 7.93
003 = 3 and in word form it is "three". There is no such thing as a decimal word!
To write the number 3000000 plus 40000 plus 8000 plus 2 plus .07 plus .003 in standard form, you would add all the numbers together to get 3,045,002.073. This number can be expressed in standard form as 3.045002073 x 10^6, where the decimal point is moved to the left to create a number between 1 and 10, and the exponent indicates how many places the decimal point was moved.
