⓵
When multiplying several factors together, an even number of negative signs will result in a positive answer.
↠ Because when you multiply two negative signs together, the negative signs turn into a positive sign, giving you a positive answer.
↠ If you have an even number of negative signs to multiply, then all your negative signs will be turned into positive signs, giving you a positive answer!
⓶
When multiplying several factors together, an odd number of negative signs will result in a negative answer.
↠ Because when you multiply a negative sign by a positive sign, the negative sign always wins, giving you a negative answer.
↠ If you har an odd number of negative signs to multiply, this means that once you are done multiplying all of the negative signs together except for the last one, you will be multiplying a positive sign with a negative sign.
↠ Here’s another way to see it : if you have 5 negative signs to multiply together, you will start by multiplying the first 2, which will give you a positive result. Then you will multiply the third and the fourth negative signs together, which will also give you a positive result. By that time, you will have two positive signs and one negative sign left, which means you will have no choice but to multiply a positive sign by the last negative sign, resulting in a negative answer!

Answer: -119, -120, and -121
Step-by-step explanation: This problem states that the sum of three consecutive integers is -354 and it asks us to find the integers. Three consecutive integers can be represented as followed.
X ⇒ <em>first integer</em>
X + 1 ⇒ <em>second integer</em>
X + 2 ⇒<em> third integer</em>
<em />
Since the sum of our three consecutive integers is -354, we can set up an equation to represent this.
X + X + 1 + X + 2 = -354
Now, we can simplify on the left side of the equation.
3x + 3 = -354
-3 -3 ← subtract 3 on both sides of the equation
3x = -357
÷3 ÷3 ← divide both sides by 3
X = -119
X ⇒ <em>first integer = </em><em>-119</em>
X + 1 ⇒ <em>second integer = </em><em>-120</em>
X + 2 ⇒<em> third integer = </em><em>-121</em>
<em />
Therefore, our three consecutive integers are -119, -120, and -121.

Answer:
The maximum number of text message John can send is 100
Step-by-step explanation:
Given as :
The phone bill of the John = $ 10 per month + $ 0.3 per text message
John want his bill amount to be less than $ 40
Let The maximum number of text message John can send = n
According to question
The total bill amount = The cost of phone plan + rate of text message
I.e $ 10 per month + $ 0.3 × maximum number of text message = $ 40
or, $ 0.3 × n = $ 40 - $ 10
Or, $ 0.3 × n = $ 30
∴ n = 
I.e n = 100
So, The maximum number of text message John can send = n = 100
Hence The maximum number of text message John can send is 100 Answer
