Fill 0 to 9 in the following space respectively to make the formula hold. Each number can only be used once □ + □ = □ + □ = □ + □
Because there is a 0, 0 must not fill in the last one. 2. And 0 can not fill in the space with a multiplication sign and the first formula, because it will cause another space to be equal to the last number. The number can not be repeated. 3. There are three spaces and two spaces connected together, that is to say, these numbers are the same
