Answer 2

Answer: -672

Step-by-step explanation: First get rid of the brackets, so multpily them by the numbers next to them. This will turn the expression into -14 x -6 x -8.

Next from left to right let’s multiply the numbers (it doesn’t actually matter which order you do it in as you will always get the same answer because it’s multiplication, it just makes it easier to do it this way.)

so -14 x -6 = 84, the numbers turn into a positive number because the minus’ cancel each other out, think about it this way, in addition, subtraction and multplication, ignore division for now, if there are an even amount of minus symbols in a sum, if the number you are in subtraction for instance that you are subtracting from is a positive number, then the number is always going to increase in value, so 14 - -6 becomes 14 + 6 which gives us 20. If the number you are again for instance subtracting from is already negative, then the number is going to decrease in value, so -14 - 6 becomes -20. If there are an odd number of minus symbols in a sum though, then if the number you are subtracting from is a negative number then it will increase in value, for instance, -14 - -6, this becomes -8, so -14 has increased its value to -8, if the number you are subtracting from is already a positive number however, then the number will decrease in value, so 14 - 6, this becomes 8. Remember this rule of you didn’t know it already. This ruke accounts to addition and multiplication as well.

So now the expression looks like, 84 x -8,

judging by the rule we just looked at, 84 will become more negative. So 84 times -8 = -672.

So our answer is -672.

Hope this helps.
