Why do scientists use symbols to represent atom when writing chemical equations?
They use symbols because the words are too long to actually write so instead they find the right symbol and write that instead. Also they must actually have a reason. I hope this helped if not I'm sorry.
How do you write math equations from your laptop keyboard?
Take a look at your (See first related link below for this) right now, just to reassure yourself. Confused by what you see? Well, this is a computer, and although it uses some traditional math symbols, it also throws in a couple special oddball symbols for mathematical operations:+ is for addition.- is for subtraction.* is for multiplication./ is for division.The only really strange symbol here is the asterisk, for multiplication. Don't use the little x! It's not the same thing. And don't waste your time hunting for the ÷ symbol. It's not there - it's / or nothing for division.Read more: See second related link for this

How do you write a expression with three terms?
To write an expression with three terms, you need to include three different parts separated by either addition or subtraction symbols. For example, an expression with three terms could be "2x + 3y - 5z". Each part of the expression (2x, 3y, and -5z) is considered a separate term. It's important to ensure that each term is distinct and clearly separated within the expression.
