Q. (iii)

(-75)+18=

Identify numbers and operation: Identify the numbers and the operation to be performed. $\newline$ We have two numbers: $-75$ and $18$ , and the operation is addition.
Perform addition operation: Perform the addition operation. $\newline$ To add $-75$ and $18$ , we combine the values, keeping in mind that $-75$ is negative and $18$ is positive. $\newline$ $(-75) + 18 = -75 + 18$
Calculate the sum: Calculate the sum. $\newline$ Since we are adding a negative number to a positive number, we find the difference between their absolute values and keep the sign of the larger absolute value. $\newline$ The absolute value of $-75$ is $75$ , and the absolute value of $18$ is $18$ . The difference is $75 - 18$ . $\newline$ $75 - 18 = 57$ $\newline$ Since the larger absolute value was from $-75$ , the result will be negative. $\newline$ So, $(-75) + 18 = -57$
