$32$ $32$

There are 3 terms. work out each one separately and and the single answers in the last step.

$23 - 12 \div 4 \times 2 + 15$ $color(magenta)(23)color(blue)(-12 div4 xx2) color(red)( +15)$

= $23 - \frac{12}{4} \times 2 + 15$ $color(magenta)(23)color(blue)(-12/4 xx2) color(red)( +15)$

= $23 - 3 \times 2 + 15$ $color(magenta)(23)color(blue)(-3xx2) color(red)( +15)$

= $23 - 6 + 15$ $color(magenta)(23)color(blue)(-6) color(red)( +15)$

To avoid confusion, write all the additions at the beginning, then the subtractions:

= $23 + 15 - 6$ $color(magenta)(23) color(red)(+15)color(blue)(-6)$

= $32$ $32$
