Ruby shorthand

Question

i don’t really get += because

a = 1
b = 2

a +=b

So in my head it goes 1 = 1+2
I don’t get this. Help

Answer 1

Would be more like a = a+b or you could write it a = 1+2, which now changes the value of a to 3 for any future references until changed again. I hope that helps.

Answer 2

Answer 3
