Integer Operations Trivia Test: Quiz

Explanation
When multiplying a positive number by a negative number, the result is always negative. In this case, when 7 is multiplied by -3, the answer is -21.

Explanation
The given question is asking for the sum of 5 and -3. When we add a positive number and a negative number, we can think of it as subtracting the absolute value of the negative number from the positive number. In this case, we are subtracting 3 from 5, which gives us 2. Therefore, the correct answer is 2.

Explanation
The given equation is -4 - 9. To solve this, we subtract 9 from -4. Subtracting a positive number from a negative number results in a more negative number. So, -4 - 9 equals -13.

Explanation
The given expression represents the division of 20 by -2. When we divide a positive number by a negative number, the result is always negative. Therefore, the answer to 20 divided by -2 is -10.

Explanation
When multiplying two negative numbers, the result is always positive. In this case, multiplying -7 by -8 gives us a positive result of 56.

Explanation
The given expression is -12 divided by -4. When dividing two negative numbers, the result is always positive. Therefore, -12 divided by -4 equals 3.

Explanation
The given expression involves adding two negative numbers, -8 and -7. When adding negative numbers, the result is always negative. In this case, -8 plus -7 equals -15.

Explanation
When subtracting a negative number from another negative number, it is equivalent to adding the absolute values of the two numbers. In this case, the absolute value of -4 is 4. So, -4 - (-4) becomes -4 + 4, which equals 0.

Explanation
The given equation (-13) + 20 equals 7. To solve this equation, we start by adding -13 and 20. When we add these two numbers, we get 7 as the result. Therefore, the correct answer is 7.

Explanation
The given equation is a subtraction problem, where we are subtracting a negative number (-9) from a positive number (3). When we subtract a negative number, it is equivalent to adding its absolute value. So, subtracting -9 is the same as adding 9. Therefore, 3 - (-9) is equal to 3 + 9, which equals 12.
