Evaluating $14.65 - 20$

To evaluate the expression $14.65 - 20$ , first determine the sign. Since a larger magnitude number is being subtracted from a smaller one, the difference will be negative. To compute the value, subtract the smaller number from the larger ( $20 - 14.65$ ). Since $20$ is a whole number, place a decimal point after the $0$ and use zeroes as placeholders to make it $20.00$ . Aligning the decimal points vertically, subtract $14.65$ from $20.00$ as if they were whole numbers, which yields $5.35$ . Finally, write the result with the correct negative sign. Therefore, $14.65 - 20 = -5.35$ .
