Question

If $P = +$, $Q = -$, $R = 	imes$, $S = \div$, then insert the proper notations between the successive numbers in the equation $60 \,\square\, 15 \,\square\, 3 \,\square\, 20 \,\square\, 4 = 20$.

Test option (b) QRPS: $60\, Q\, 15\, R\, 3\, P\, 20\, S\, 4 = 60 - 15 	imes 3 + 20 \div 4$. Applying BODMAS: $60 - 45 + 5 = 20$. This equals 20, so option (b) QRPS is correct.
