First one is 46.
Think of rows.
38 rows of 50 is obtained when we subtract
8 rows of 50 away from 46 rows of 50.

Settle the brackets first.
Division and multiplication next, whichever comes first
Addition and subtraction last, whichever comes first.
100 / 4 + 6 x (10 - 2)
= 100 / 4 + 6 x 8 (brackets first)
= 25 + 6 x 8 (division before addition)
= 25 + 48 (multiplication before addition)
= 73 (addition)
