What is the History of Pascal's triangle?
The set of numbers that form Pascal's triangle were well known before Pascal. But, Pascal developed many applications of it and was the first one to organize all the information together in his Traité du triangle arithmétique (1653). The numbers originally arose from Hindu studies of binomial numbers and the study of figurate numbers. The earliest explicit depictions of a triangle of binomial coefficients occur in the 10th century in commentaries on the Chandas Shastra, a book by Pingala written between the 5th and 2nd century BC.
What are coefficients of an expression?
A numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g., 4 in 4xy).
What is the correct way to write out decimals in words?
When writing a decimal out in words, the numbers before the decimal are written as if they are whole numbers, and the numbers after the decimal are read as digits. Therefore, for example, 150.35 is read one hundred and fifty point three five.
What is The amount of increase or decrease in a function usually written as a fraction?
When writing a function, the decreasing or increasing numbers are known as variables. Before those variables are known, they are written as alphabetical letters, often "x," "y" or "z."
What numbers come before zero?
If you're talking about whole numbers, then negative integers. But since fractions and decimals are numbers, and are not integers, anything with a negative symbol before it comes before zero. Examples: -0.34, -40, -2/3
What means a number before a chemical formula for instance 3co2?
Coefficients :)
What do you call the numbers used to balance equations?
The numbers placed immediately before formulas of compounds and/or elements involved in the reaction are called "coefficients" and those placed immediately after element symbols, depressed below the typographical line of the element symbol are called "subscripts". The subscripts show the number of atoms of a particular element in a formula unit of a molecule or other compound.
Numbers that precede symbols and formulas in a chemical equation?
The numbers that precede symbols and formulas in a chemical equation represent the balance of atoms or molecules on each side of the equation. These numbers are coefficients and indicate the ratio in which the reactants combine or products are formed in the chemical reaction. They ensure that the law of conservation of mass is satisfied in the reaction.
Is it true or false when adding coefficients I can only add them to the beginning of a chemical formula or element.?
False. Coefficients can be added before any chemical species in a chemical equation to balance the number of atoms on each side. The coefficients indicate the relative amounts of each substance involved in the reaction.
What part of the chemical formula indicates the number of molecules or atoms involved?
The answer is 'subscript'
Where does coefficient belong in the chemical formula?
The coefficient in a chemical formula is the large number before each of the reactants or products. In the balanced equation for the synthesis of water: 2 H2 + O2 --> 2 H2O The number 2 in front of the H on both sides of the arrow are the coefficients.
What is understood if no coefficient is written before a formula in a chemical equation?
If no coefficient is written before a formula in a chemical equation, it is understood to have an implied coefficient of 1. This means that there is one molecule or formula unit of that particular substance involved in the reaction.
What is the formula for consecutive numbers?
x-1 and x+1 are consecutive to x, the first before it and the second after it.
When balancing an equation you can only change the which tells you the number of particles that participate in the reaction and comes before the symbol?
You can only change the coefficients when balancing an equation. The coefficients are the whole numbers that come before the chemical symbols of the reactants and products, indicating the ratio of moles of each substance in the reaction.

How and where is the dollar sign written?
It is written before numbers and it is a capital "S" with one or two lines from top to bottom of the letter.
Are chemical equations balanced by changing the subscripts of the molecules?
No, chemical equations are balanced by adjusting the coefficients in front of the chemical formulas. Changing the subscripts would alter the actual chemical identities of the substances involved.
