$15$ $15$

Count the number of terms first. Each term will simplify to to a single answer and they are only added or subtracted in the last line.

Within in a term - do brackets first, then the strongest operations (powers or roots), and then multiplication and division.

$2^{3} + 8 \div 4 \times 2 + 3 \leftarrow$ $color(purple)(2^3)color(red)( + 8div4xx2)color(blue)(+3)" "larr$ there are 3 terms.

= $8 + \frac{8 \times 2}{4} + 3$ $color(purple)(8)color(red)( + (8xx2)/4color(blue)(+3)$

= $8 + 4 + 3 \leftarrow$ $color(purple)(8)color(red)( + 4)color(blue)(+3)" "larr$ add from left to right

= $15$ $15$
