The symbol for imaginary numbers is?
An imaginary number is symbolized by the letter i
Can a number be imaginary but not pure imaginary?
Yes. The number 1 + i is imaginary but not pure imaginary, while 5i is pure imaginary.
Does the imaginary or real part come first when writing a complex number?
The standard written form of a complex number is to first write the real part of the number, and then write the imaginary part; e.g. x+yi or 3+7i.
Is the difference of a complex number and its conjugate a real imaginary or pure imaginary number?
It is a pure imaginary number.Since (a+bi)-(a-bi) = 2bi, it is a pure imaginary number (it has no real component).
Is -23 an imaginary number?
No, but √-23 is. An imaginary number is the square root of a negative number.

What does i mean in mathematics?
The symbol "i" is an imaginary number used in algebra, equal to the square root of negative one.
The square root of -17 is what kind of number?
An "imaginary" number. Those number are called imaginary for historical reasons, but they have very "real" practical applications. The result is written as root(17)i (replace root(17) with the square root symbol).
Can a number be imaginary but not pure imaginary?
Yes. The number 1 + i is imaginary but not pure imaginary, while 5i is pure imaginary.
Can a no real number be a pure imaginary number?
If a number is pure imaginary then it has no real component. If it is a real number, then there is no imaginary component. If it has both real and imaginary components, then it is a complex number.
Can you divide an imaginary number by a real number?
an imaginary number is imaginary so no (i guess) this answer kind of sucks
How do you simplify the imaginary number -125?
-125 is NOT an imaginary number.
Are negative numbers real numbers?
Yes, any positive or negative number is a real number, including 0. Non real (or imaginary) numbers are the ones that have an "i" or "j" such as j1.5 or 1.5i The imaginary numbers come from expressions like sqrt(-1), its impossible to come up with a real answer so the imaginary one would be 1i or i
Does the imaginary or real part come first when writing a complex number?
The standard written form of a complex number is to first write the real part of the number, and then write the imaginary part; e.g. x+yi or 3+7i.
What does 7 divided by imaginary number equal?
That quotient would be an imaginary number. The actual number depends on exactly what imaginary number you divide the 7 by.
Is the difference of a complex number and its conjugate a real imaginary or pure imaginary number?
It is a pure imaginary number.Since (a+bi)-(a-bi) = 2bi, it is a pure imaginary number (it has no real component).
Is -23 an imaginary number?
No, but √-23 is. An imaginary number is the square root of a negative number.
