Subject + 等于 + Noun/Clause
The word 等于 (děngyú) literally means "equal to" and is used to equate two things or situations. Beyond mathematics, it is commonly used figuratively to say that one action or situation is essentially the same as another. For example, you can use 等于 to argue that doing nothing is basically the same as giving up.
