Form two numbers. The sum of them must be $100$.
For the first one you must use the digits $4$, $5$ and $6$ taken exactly once in this order. You cannot use other digits.
For the second one you must use the digits $7$, $8$ and $9$ taken exactly once in this order. You cannot use other digits.
The operations you may use for forming each of the numbers are $x + y$, $x - y$, $x \times y$ and $x \div y$. Division is math division, you cannot use computer integer division where
4/5 = 0. Operator precedence is respected. Each operation may be used multiple times
You cannot use other symbols (except $456789+-\times\div)$
- 1st number: $4\times5-6$
- 2nd number: $7+89$
Sum is wrong $14+96=110 \neq 100$, but everything else is ok.
