Which Operator Asked Which Question

Five things this topic established, and where each one was.

What the topic established, and which card it was on
The thing	Where
The operand types choose what a symbol does	One Symbol, Several Jobs
`=` assigns, `==` asks about identity, `.equals` asks about contents	Assigning, Comparing Identity, and Comparing Contents
`&&` and `\|\|` stop early, which is what makes a null guard work	Short-Circuiting, and the Null Check That Leans On It
`*`, `/` and `%` bind tighter than `+` and `-`	Why 5 + 3 * 2 % 4 Is Not Read Left to Right
`i++` produces the old value; `++i` produces the new one	Why j Is 5 After int j = i++

When an expression surprises you, look at the types and the grouping before you look at the operator. Both of those were decided by the compiler, and neither of them is visible in the line you read.
