This problem should be understood as the low level of people draw,

Starting from the test, you back the answer,

CodePudding user response:

This topic is really bad to answer, determines the operation order to know the answer,

CodePudding user response:

The right hand side according to the priorities
To calculate the right a=3, this is a 3
And then calculate a + 3=6
And then calculate a *=6, know at this point a is above 3, so the calculation results for a=3 * 6=18, at this point a is 18
Is 18, and then calculate a +=a=18 + 18=36
