Exponents
The difference between brackets and no brackets.
-26=-64 -(2)(2)(2)(2)(2)(2)=-64
(-2)6=64 (-2)(-2)(-2)(-2)(-2)(-2)=64
If the negative is inside the brackets and the exponent is a even number. The answer then will be positive.
If the negative is outside the brackets and the exponent is even or odd the answer is negative.
Two rabbits doubles every hour. How many rabbits will there be after 6 hours?
The answer is 64 because 2×2=4×2=8×2=16×2=32×2=64
For question 3
Fake accounts would effect me because you really don’t know if this person is real. The fake people can spread bad and fake information and if the information is bad or disrespectful everyone will go at the person who actually has the name that the fake person has put on their account. Fake people might try to target younger people because they know that older adults can figure out that they are fake. Fake people can also try to take your credit card number and bank information if you are a fried of the actual name that they put on their social media page.

Coca-Cola had 14,490 people vote- %67.28
Pepsi had 7046 people vote- %32.72
This vote is voluntary response because they have a vote and ask people to participate. The people have a choice whether to vote or not to vote so it is a voluntary response. The website has many other votes that people can chose to participate in.

Question 1:What is the difference between and ?
The difference betweenthe two questions is that =8 and =9
Question 2: what is the difference between and
The difference between the two questions is that the one in brackets would be positive 16 and the one without the brackets would be -16

A and E are Equivalent: In E the subtraction symbol cancels out the negative symbol.
B and F are Equivalent: -5 -11 is the same as saying -5+(-11)
C and G are Equivalent: In C two negatives equal a positive so it really is just -5+11
Some of the statements have the same answer even though the numbers in the equation are arranged differently.That is because the positive/negative numbers have an impact on if it is positive or negative sum. Also the addition and subtraction symbols can determine if your answer is negative or positive.
One of the things that I learned is that you can have the same answer for two different looking equations.
Some things that students should remember is that when you subtract a negative integer that integer becomes positive. When you add a negative integer to a positive integer the sum is negative.
