Separate operations from operands using space: a + b, not a+b. However, a/b, not a / b.

Use ^ for exponentiation: a to the b power is a^b.

Use parentheses when required, but also to clarify: (ab)/(c^2) is better than ab/c^2 even though normal rules of parentheses use do not require parentheses.

For square root, use ^(1/2): (a^2 + b^2)^(1/2) = c gives the length of the hypotenuse of a right triangle.

For other functions use typical abbreviations: sin(x), atan(1)

Use spaces around relation signs: a < b, not a<b.
