Question

Find: $(-7)-8-(-25)$

Answer 1

Let's find the value of: $(-7)-8-(-25)$

$=-7-8+25$ [ as $(-)\times (-)=(+)$ ]

$=-15+25$ [ to add two negative integers, we add the absolute value of the integers and put a $\text{'}+\text{'}$ sign to the result ]

$=10$ [ to add a positive and a negative integer, we subtract the integer with the smaller absolute value from the greater and put the sign of the number with a greater absolute value to the result ]

Hence, $(-7)-8-(-25)=10$
