When you square a negative number is it positive or negative?
The square of a real number is always positive no matter which real number you start with. Therefore, a negative number squared is positive. For example: 2 * 2 = 4, -2 * -2 = 4.
What is the quotient of 2 integers with the same sign?
It would be a positive number. A negative number divided by a negative number would be positive. A positive number divided by a positive number would also be positive. So, the quotient of 2 integers with the same sign will be a positive number, regardless of which sign the two numbers had.
What is the least positive number that is divisible by three different primes?
30, which is the smallest positive integer divisible by the first three primes: 2, 3 and 5.
How do you divide 10 by -2?
12
What is the sum of the first 100 positive even integers?
use this formula: S=(N/2)(F+L) S= the sum of the first 100 positive even integers N= the number of terms F= first term L=last term Since we are using the first 100 positive integers we will replace "N" with 100. so it will look like this : S=(100/2)(F+L) Next we must substitute the "F" with the first positive term which is the number 2. So now it looks like this: S=(100/2)(2+L) We use the number 2 because our positive integers are 2,4,6,8,10,12...... you get the picture. Now we must substitute the "L" with the last positive term which is 200. As you probably guessed it will look like this: S=(100/2)(2+200) We use the number 200 because it is the last positive even integer. If we used 202 then that would have meant we used the 101th positive even integer and we don't want to do that. == == We should solve the numbers inside the parenthesis first. S=(100/2)(2+200) 100 divided by 2 = 50 So: S=50(2+200) 2+200=202 That means: S=50(202) 50 x 202 = 10,100 Finally: S=10,100 There you go! Wasn't that easy? Note: This formula only works if you are looking for the sum of the first 100 positive or negative, even or odd integers. It sucks cause this formula is the Bomb right? Oh well
A positive number minus a positive number is always positive?
no not always. as long as the first number is bigger than the second number. if it is not, the answer is negative. 7-5=2 5-7= -2
In subtraction 2 negatives equal what?
if the first negative is samller than the second its positive but if the first one is a larger number than the second then its a positive
A negative number minus a negative number?
is a negative number plus another number...., but not neccessarily a positive number b/c the first number may be greater than the second e.g. -5-(-2) that is -5+2, which is -3 2 negatives make a positive
What is the first positive non Fibonacci number?
Since zero is both a positive number (defined as such), and not part of the Fibonacci sequence, then the first positive non-Fibonacci number is zero (0). If zero does not fit in you definition of positive number, then the answer would be four (4).
Does a negative number plus a positive number equal a positive?
Not if the negative number is greater than the positive. If the positive number is greater than the negative, it logically follows that the resulting number would be positive. Example: -2 + 1 = -1 -2 + 2 = 0 -2 + 3 = 1
How do you subtract a positive number from positive number if the first number smaller?
SO pretty much, you would fit the smaller number into the bigger number, and turn the extras into a negitave (ex. 6-8=(-2)
Multiply a negative number by a negative number?
a positive number..... 2 negatives=positive
A positive integer minus a positive integer is always positive?
no it depends on if the first number in the equation is bigger or smaller than the second ex. 2-3= -1
What is negative plus positive?
It depends on the magnitude of the negative and positive values. Equal magnitudes equal zero. -2 + 2 = 0 Larger negative number than positive number equals a negative number. -3 + 2 = -1 Smaller negative number than positive number equals a positive number. -2 + 3 = 1
When you square a negative number is it positive or negative?
The square of a real number is always positive no matter which real number you start with. Therefore, a negative number squared is positive. For example: 2 * 2 = 4, -2 * -2 = 4.
What is the quotient of 2 integers with the same sign?
It would be a positive number. A negative number divided by a negative number would be positive. A positive number divided by a positive number would also be positive. So, the quotient of 2 integers with the same sign will be a positive number, regardless of which sign the two numbers had.
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
