wat are the square brackets that are found in algebra

Just one way of grouping the terms in an algebraic expression. You can also us () or {} besides []. In certain contexts each of these symbols can have other meanings too, but the context should make it clear what is meant. Typically we use () first, then [] and {}.

Square brackets, also known as brackets or box brackets, are a type of grouping symbol used in algebraic expressions. They can be used to group terms together to indicate that those terms should be treated as a single entity.

In algebra, expressions can involve various operations such as addition, subtraction, multiplication, and division. When an expression becomes more complex, it can be helpful to use grouping symbols like square brackets to clarify the order in which the operations should be performed.

For example, consider the expression 3 * (4 + 2). The parentheses here indicate that the addition operation inside them should be done first. The result is 3 * 6 = 18.

Now, let's say we have the expression 3 * [4 + 2]. The square brackets here serve the same purpose as parentheses – they indicate that the addition should be done first. So, again, the result is 3 * 6 = 18.

In general, when evaluating an expression with square brackets, you perform the operations inside the brackets first and then apply any operations outside the brackets.

It's important to note that square brackets can also be used for other purposes in different contexts, such as in matrices or for denoting intervals. However, in the context of algebraic expressions, square brackets are primarily used as grouping symbols to specify the order of operations.
