200-[(50-4)×3+5]" title="200 - ((50 - 4) \times 3 + 5)" alt="200 - ((50 - 4) \times 3 + 5)" align="absmiddle" class="latex-formula">

Answer 1

200 - [ ( 50 - 4 ) × 3 + 5 ]
= 200 - [ 46 × 3 + 5 ]
<Put brackets around the 2 number that enclose the times sign as a reminder to do that first>
= 200 - [ ( 46 × 3 ) + 5 ]
= 200 - [ 138 + 5 ]
= 200 - (143)
= 57

Hope this helps!
