What does the I mean in math?
i is a number. It is defined as the number which, when squared, yields -1. No “real” numbers (numbers on the number line) meet this criterion. So i is a number that’s not on the number line. So you need to expand to the Complex Plane. The old familiar number line is the horizontal line across the center. That’s where all real numbers are.
What does I represent in math?
[math]imath] is a number, just not a real number. It instead is what is known as an imaginary number, or more generally when combined with real numbers a complex number. When you multiply two real numbers together you get another real number.

What is the number i?
The unit imaginary number, i, equals the square root of minus 1. Imaginary Numbers are not "imaginary", they really exist and have many uses.
What does the i mean after a number?
With imaginary numbers, when you square them, the answer is negative. They are written like a real number, but with the letter i after them, like this: 23iThe letter i means it is an imaginary number.
What is 4i in math?
So, the square root of -16 is 4i. As a double check, we can square 4i (4*4 = 16 and i*i =-1), producing -16. All negative square roots are called "imaginary numbers" (now you know where that letter 'i' comes from). Complex Numbers.
What are the rules for i in algebra?
To determine the value of i raised to a power greater than two, we rewrite the term using exponent rules. Remember that i^2 = -1 and i^4 = 1. Therefore, any exponent of i that is a multiple of four will equal one; any even exponent not divisible by four will equal negative one.
The letter i - math word definition
Definition and meaning of the math word i. i. The letter i is used to signify that a number is an imaginary number. It stand for the square root of negative one. In electrical engineering it is often replaced by the letter j to avoid conflict with the symbol for current. See Imaginary numbers.

Imaginary numbers are numbers that are not real. Learn the definition, rules, arithmetic operations, examples with a detailed explanation of complex numbers at BYJU'S.
Using i
Interesting! We used an imaginary number (5 i) and ended up with a real solution (−25).
Unit Imaginary Number
The square root of minus one √ (−1) is the "unit" Imaginary Number, the equivalent of 1 for Real Numbers.
Imaginary Numbers are not "Imaginary"
Imaginary Numbers were once thought to be impossible, and so they were called "Imaginary" (to make fun of them).
Imaginary Numbers are Useful
Imaginary numbers become most useful when combined with real numbers to make complex numbers like 3+5i or 6−4i
Interesting Property
The Unit Imaginary Number, i, has an interesting property. It "cycles" through 4 different values each time we multiply:
Conclusion
Imaginary Numbers are not "imaginary", they really exist and have many uses.
What is the meaning of "n" in math?
1. Used for emphasizing that several equations have to be considered as simultaneous equations; for example,#N#{ 2 x + y = 1 3 x − y = 1 {displaystyle textstyle {begin {cases}2x+y=1\3x-y=1end {cases}}}#N#.
What is mathematical symbol?
A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various types, ...
What does the symbol infty mean?
1. The symbol is read as infinity. As an upper bound of a summation , an infinite product, an integral, etc., means that the computation is unlimited. Similarly,#N#− ∞ {displaystyle -infty }#N#in a lower bound means that the computation is not limited toward negative values.
What is the entry name of a symbol?
For most symbols, the entry name is the corresponding Unicode symbol . So, for searching the entry of a symbol, it suffices to type or copy the Unicode symbol into the search textbox. Similarly, when possible, the entry name of a symbol is also an anchor, which allows linking easily from another Wikipedia article.
