$$10+10\div10-10\times10=10$$

Solution

Expression : $$10+10\div10-10\times10=10$$

(A) : $$10-10\div10+10\times10$$

= $$10-1+100=109\neq10$$

(B) : $$10\div10+10-10\times10=10$$

= $$1+10-100=-89\neq10$$

(C) : $$10\times10\div10-10+10=10$$

= $$10-10+10=10$$

(D) : $$10\div10+10-10\times10=10$$

= $$1+10-100=-89\neq10$$
