Exponential arithmetic addition

Venous Nomogra.phs, The alignment chart is restricted neither to addition operations, nor to three-variable problems. Alignment charts can be used to solve most mathematical problems, from linear ones having any number of variables, to ratiometric, exponential, or any combination of problems. A very useful property of these alignment diagrams is the fact that they can be combined to evaluate a more complex formula. Nomographs for complex arithmetical expressions have been developed (108). 

A major benefit of presenting numbers in scientific notation is that it simplifies common arithmetic operations. The simplifying abilities of scientific notation cire most evident in multiplication and division. (As we note in the next section, addition and subtraction benefit from exponential notation but not necesscirily from strict scientific notation.)... 

The arithmetic operators are addition (-I-), subtraction (-), multiplication ( ), division (/) and exponentiation ( ). Other types of operator are described in Chapter 3. 

The arithmetic operators for addition, subtraction, multiplication, division and exponentiation are familiar ones and have already been mentioned in Chapter 1. 

In addition to basic arithmetic and algebra, four mathematieal operations are used frequently in general chemistry manipulating logarithms, using exponential notation, solving quadratic equations, and graphing data. Eaeh is diseussed briefly below. 

The arithmetic operations in a spreadsheet are addition, subtraction, multiplication, division, and exponentiation (which uses the symbol ). The order of operations in formulas is first, followed by and / (evaluated in order from left to right as they appear), finally followed by + and — (also evaluated from left to right). Make liberal use of parentheses to be sure that the computer does what you intend. The contents of parentheses are evaluated first, before carrying out operations outside the parentheses. Here are some examples ... 

Lua supports the usual array of arithmetic operators + for addition, - for subtraction, for multiplication, / for division, % for modulo, for exponentiation and unitary - before any number. The supported relational operators are ...
