To solve this expression, we need to follow the order of operations (PEMDAS/BODMAS).

First, we perform the multiplication and division from left to right:
12345 × 67890 = 839,034,050
839,034,050 - 54321 = 838,979,729
838,979,729 ÷ 12344 = 68,000.000162

Next, we perform the addition and subtraction from left to right:
68,000.000162 + 67890 = 67,962.000162
67,962.000162 + 13569 = 68,531.000162

Therefore, the value of the expression 12345×67890-54321/12344×67890++13569 is approximately 68,531.000162.
