Does 2 to the negative power of 2 equal negative 4?
No Actually... x^(-y) is equal to 1/x^y. 2^(-2) is equal to 1/2^2 which is equal to 1/4 or 0.25.
If The product of x and negative 4 is 8 more than 2 added to negative 5 times that number what equation could be used to solve for x?
x*-4=8+(2-5*x) =-4x=8+2-x5 x*-4=8+(2-5*x) =-4x=8+2-x5 x*-4=8+(2-5*x) =-4x=8+2-x5
What is a positive integer times a negative integer?
negative read this : "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)"
What integer divided by the sum of negative 4 and positive 6 equals negative 15?
Set up an equation using x for the integer. The equation would be: x/(-4+6)=-15 Firstly find the sum of -4 and 6. It would be 2. The equation is now: x/2=-15 Multiply both sides by 2. This means that: x=-30 Plug it back into the equation to check: -30/(-4+6)=-15 -30/2=-15 -15=-15 It works therefore -30 is the integer that when divided by the sum of negative 4 and positive 6 equals negative 15.
What does a positive number multiplied by a negative number equal?
A negative times a positive equals a negative. For example 2 x -16=-32 A negative times a negative equals a positive For example -2 x -16=32 A positive times a positive equals a positive For example 2 x 16=32 Remember that this rule only applies to multiplication and it doesn't matter if the smaller number has the negative sign or the bigger number has the negative sign; It will still be a negative. Also remember that it doesn't matter whether its a negative times a positive or a positive times a negative ; It remains a negative regardless of the order of the signs. Lastly remember that a negative times a negative will always be a positive and a positive times a positive will always be a positive. For example -2 x 105=-210 105 x -2=-210 2 x -105=-210 -105 x 2=-210 105 x 2 =210 -105 x -2 =210 So this means that a negative times a positive will always equal a negative, a negative times a negative will always equal a positive, and a positive times a positive will always equal a positive. Now if you were dealing with more than two numbers with both negative and positive signs, the easiest way to know whether the answer will come up as a negative or positive is to imagine two negative signs merging into a positive sign and any remaining negative sign that does have another negative sign to pair with remains a negative;You can only combine negative signs in pairs(for example -2 x -2 x -2=4 x -2=-8).Now if you have a situation where you were able to pair up all of the negative signs into positives signs and have no negative signs left over, then the answer will be a positive (for example -2 x -2 x -2 x -2 x 2=16 x 2=32).
What is negative divided a positive?
Here is a table for multiplication / division of positive/negative numbers. X/ + = + X/ - = - X/ + = - X/ - = + NB 'X/' means multiply or division. NNB If there is no sign in front of a number treat it as positive (+). e.g. 2 X 2 = 4 (Note ; no symbols, so it is treated as plus(+)) 2 X -2 = -4 -2 X 2 = -4 -2 x -2 = (+)4
What is x plus 4 negative 2?
It is x+2
What are the rules for multiplying or dividing negative and positive numbers?
Positive x Positive = Positive: 3 x 2 = 6Negative x Negative = Positive: (-2) x (-8) = 16Negative x Positive = Negative: (-3) x 4 = -12Positive x Negative = Negative: 3 x (-4) = -12
What does a negative number times a negative number equals?
negative multiply by negative is positive. While negative added with negative is negative. E.g. - 2 x -2 is 4 while -2 + -2 is -4
What is negative 2 to the power of 2?
-2 x -2 = 4
Why a negative number times a positive number will give a negative number?
Becuase in the rule of laws of signs, when you multiply or divide a number that is positve by a negative number or a number that is negative by a positive number (same thing), the product/answer will always be a negative number. But when you multiply/divide a positive number by positive or negative by negative, the product/answer will always be positive number E.g: -2 x 2= -4 / 2 x (-2)= -4 -2 -:- 2= -1 / 2 -:- (-2)= -1 E.g: 2 x 2=4 / -2 x (-2)=4 2 -:- 2= 1 / -2 -:- (-2)=1

How can a negative and a negative be a positive?
I presume you're asking why if you multiply two negative numbers, you end up with a positive number? Partly, it's because it's the convention in maths; but why was that convention chosen? Start with multiplying a positive and a negative: +2 x -2 = -4 To put it in practical terms; if you owe two people £2, then you owe a total of £4. So if +2 x -2 = -4 it makes sense for -2 x -2 to equal +4 - the alternative is for -2 x -2 to equal -4 and you end up with +2 x -2 = -2 x -2 which gives you +2 = -2 which is clearly wrong.
