What are the Basics of Algebra? The basics of algebra includenumbers, variables, constants, expressions, equations, linear equations, and quadratic equations. Apart from these, it involves the basic arithmetic operations of addition, subtraction, multiplication, and division within the algebraic expressio...
Vedic Mathematics can definitely solve mathematical numerical calculations in faster way. Some Vedic Math Scholars mentioned that Using Vedic Maths tricks you can do calculations 10-15 times faster than our usual methods. I agree this to some extent because some methods in Vedic Mathematics are reall...
Two complex numbers Z and W are related by the formula W = {Z + 1} / {1 - Z}. What is W if Z = 1.5 i? Suppose z varies directly with y and directly with the cube of x. If z = 486 when x = 3 and y = 9, what is z when x = 12 and y = 1? Solve for Z, and...
At the store, ask your child questions to focus her attention on the shapes that you see. Ask her to find, for example, items that have circles or triangles on them or boxes that are in the form of a cube or a rectangular solid. ...
To find the geometric mean of the observations 125, 729, and 1331, we can follow these steps:Step 1: Identify the numbers The numbers given are: - \( a = 125 \) - \( b = 729 \) - \( c = 1331 \)Step 2: Use the for
Prime numbers need to have exactly two factors. Why is 2 a prime number? 2 is a prime number because its only factors are 1 and itself. Is 51 a prime number? 51 is not a prime number because it has 3 and 17 as divisors, as well as itself and 1. In other words, 51 has four...
What is the sum of the first 5 numbers squared? The question is ambiguous.Does it want the sum of the squares, or the square of the sum ? They're different.Here are both:1). Sum of the squares: . (1)2 + (2)2 + (3)2 + (4)2 + (5)2 = 1 + 4 + 9 + 16 + 25 = ...
If we then introduce the natural numbers by the formula (3), then an easy induction using (4) shows that with the periodic convention for . As the are increasing in (even for ), we see that is the largest power of that divides the right-hand side of (5); as is odd, we ...
When the “sphere trick” is applied to tangled messes it doesn’t necessarily have to give you integer numbers until the spheres are small enough. With fractals there is no “small enough” (that should totally be a terrible movie tag line), and you find that they have a dimension t...
