order of operations:);
evaluate powers first, parenthesis second, multiplication and division third (if there is a combination of the two it doesn't matter the order you evaluate), and addition and subtraction last (like multiplication-division it doesn't matter the order you evaluate these two, a helpful tool for this step is to change all minus operations to plus negative).

The sum of 4 and 12 as an algebraic expression is represented as 4 + 12. This expression simplifies to 16, as addition is a basic arithmetic operation that combines two numbers to give a single value. In algebra, the addition symbol "+" is used to denote the operation of adding two or more terms together.

In Evaluating Expression first,replace each letter in the expression with the assigned value. second,perform the operations in the expression using the correct order of operations and the last you got the answer

Yes. In general, you can combine expressions into more complicated expressions. For example, adding an expression to another expression will, again, yield an expression.
First evaluate all powers. Then evaluate multiplications and divisions, from left to right. Then evaluate additions and subtractions, also from left to right.Parentheses change the order of operations: you must evaluate anything in parentheses first, before combining it with anything outside the parentheses. Within the parentheses, the first rule also applies (first evaluate powers... etc.).Parentheses can be implied in some cases. For example, in fractions, you have to evaluate the numerator and the denominator separately, before carrying out the division of numerator / denominator. Also, in the case of powers, e.g. 25+3, the exponent has to be evaluated before the power. In the example, you add 5+3 before calculating the power.
A numerical expression is defined as a combination of numbers and one or more operation symbols. An example is 5 + 7 - 1.
First evaluate anything within parentheses. Also evaluate any exponents before doing further operations. Then do all multiplications and divisions from left to right, then do all additions and subtractions from left to right.If an expression has a horizontal line (i.e., a fraction), that replaces a pair of parentheses: both the upper and lower part must be evaluated first, before doing the division.
Evaluate the criteria before executing the conditional expression. In pseudocode:result1 = evaluate( criteria1 );result2 = evaluate( criteria2 );if( result1 && result2 ) initiate_event;Note that this is not the same as the following:if( evaluate( criteria1 ) && evaluate( criteria2 )) initiate_event;If the evaluation of criteria1 fails for any reason, then the whole expression fails and criteria2 is never evaluated. so if the evaluations must be done independently of each other, then they must be done prior to the conditional expression, storing the results for use in the conditional expression.
The standard Boolean operators are AND, OR and NOT. From these, Boolean algebra derives 3 more "derived" operators--material implication, exclusive or, and equivalence. They are used to evaluate a Boolean expression. These expressions all evaluate to either TRUE or FALSE.
There are an infinite number of operations for integer and different rules will apply for different operations. The question needs to be more specific.
