Solution

14. $25 + (-27) + (-43) - (-10) \times (-44)$

Step 1: Simplify the first expression

Given: \[ 25 + (-27) + (-43) - (-10) \times (-44) \]

First, simplify the multiplication: \[ -10 \times -44 = 440 \]

Now substitute back into the expression: \[ 25 + (-27) + (-43) - 440 \]

Step 2: Perform the addition and subtraction

Combine the terms step by step: \[ 25 - 27 = -2 \] \[ -2 - 43 = -45 \] \[ -45 - 440 = -485 \]

\[ \boxed{-485} \]

Step 1: Simplify the second expression

Given: \[ 6 - \left( \frac{72}{4} + (-35) \right) \]

First, perform the division: \[ \frac{72}{4} = 18 \]

Now substitute back into the expression: \[ 6 - (18 + (-35)) \]

Step 2: Simplify inside the parentheses

Combine the terms inside the parentheses: \[ 18 + (-35) = 18 - 35 = -17 \]

Step 3: Perform the final subtraction

\[ 6 - (-17) = 6 + 17 = 23 \]

Final Answer for Question 16

\[ \boxed{23} \]

Step 1: Simplify the third expression

Given: \[ -37 + 16 \times 25 \]

First, perform the multiplication: \[ 16 \times 25 = 400 \]

Now substitute back into the expression: \[ -37 + 400 \]

Step 2: Perform the addition

\[ -37 + 400 = 363 \]

Final Answer for Question 18

\[ \boxed{363} \]
