Example of Evaluating $37.42 - 50$

To evaluate the expression $37.42 - 50$ , 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 numerals ( $50 - 37.42$ ). Since $50$ is a whole number, place a decimal point after the $0$ and use zeros as placeholders to make it $50.00$ . Aligning the decimal points vertically, subtract $37.42$ from $50.00$ as if they were whole numbers, which yields $12.58$ . Finally, write the result with the correct negative sign. Therefore, $37.42 - 50 = -12.58$ .
