Another way of thinking
Divide the expression by where the plus or minus signs occur outside the brackets and then combine these answers at the end

2 ⁴/ 15 + 1 / (1+3)*2Work out the red and stop as you have reached a plus sign 16/15.

Now 1/4*2 do this in the order you say it, so one divided by four is a quarter multiplied by 2 is 1/2 16/15 + 1 / 2 = 47 / 30
