Find out the two signs to be interchanged to make the following equation correct.
$$10 + 10 \times 10 - 10 \div 10 = -89$$
Expression :Â $$10 + 10 \times 10 - 10 \div 10 = -89$$
(A) :Â $$-$$ and $$\times$$
L.H.S. $$\equiv10+10-10\times10\div10$$
= $$20-10=10$$
(B) :Â $$\times$$ and $$\div$$
L.H.S. $$\equiv10+10\div10-10\times10$$
= $$10+1-100=-89=$$ R.H.S.
=> Ans - (B)
