B-brackets
O-of
D-division
M-multiplication
A-addition
S-subtraction
2/5÷8/25-[3/4+{2/6+8/42}-2/4]
= 2/5÷8/25-[3/4+{14/42+8/42}-2/4]
= 2/5÷8/25-[3/4+{22/42}-2/4]
= 2/5÷8/25-[3/4+11/21-2/4]
= 2/5÷8/25-[3/4+11/21-2/4]
= 2/5÷8/25-[107/84-2/4]
= 2/5÷8/25-65/84
= 2/5 x 25/8 - 65/84
= 5/4 - 65/84
= 10/21
