★ -159

$\sf{\huge{\underline{\purple {Solution :-}}}}$

(-1){(-5) + (- 25)} (-7) – (8 - 10) (-4)

Based on BODMAS Rule

➝ (-1 - 5 ) + ( - 25 ) × (-7 ) - ( 8- 10 ) × (-4)

➝ -6 + (-25) × -7 - (-32) + (-10)

➝ -6 - 175 + 32 - 10

➝ - 181 +32 - 10

➝ - 149 -10

➝ -159

BODMAS =

• Bracket
• Of
• Division
• Multiplication
• Addition
• Subtraction

First we have to solve the brackets then, We have to divide all divisible factors then we have to multiply the numbers needed to be multiplied . Then add all the numbers by sign convention then subtract all the term to reach the final answer.
