How do you find antilog of a negative number using a log table?

Answer 1

Well, isn't that just a happy little question! To find the antilog of a negative number using a log table, you can start by taking the absolute value of the negative number to make it positive. Then, look up the positive number in the log table to find its corresponding antilog. Remember, there are no mistakes in math, just happy little accidents!

Answer 2

To find the antilog of a negative number using a log table, first, add the absolute value of the negative number to the characteristic of the log table. Next, locate the resulting number in the log table to find the corresponding mantissa. Finally, take the antilog of the mantissa to get the final answer. Remember to consider the negative sign of the original number when determining the final result.

Answer 3

Well, darling, to find the antilog of a negative number using a log table, you first need to find the positive equivalent of the negative number. Add the negative number to the log base, and then look up the result in the log table to find the antilog value. Just remember, math doesn't have time for negativity, so keep it positive!

Answer 4

1. Ignoring the minus sign, separate the number into the whole number part and the decimal part.
2. Add 1 to the whole number part
3. Subtract the decimal part from 1.
4. Look up the result of step 3 in the [anti-]log table
5. Divide the result of step 4 by the base to the power of the number found in step 2.

Due to step 5, it is better to work with common logs (logs to base 10) when using log tables.

Example:

Find the anti-log to base 10 of -2.123:

1. -2.123 separates out into 2 and 0.123
2. 2 becomes 2 + 1 = 3
3. 0.123 becomes 1 - 0.123 = 0.877
4. Look up 0.877 → 7.53
5. 7.53 ÷ 103 = 0.00753

→ anti-log to base 10 of -2.123 is [approx] 0.00753
