Answer:
Explanation:
Using addition, subtraction, multiplication, or division, there is fundamentally only one way to make the target number from the four given numbers using each one once:
multiply 7 and 3, add 9 and subtract 14:
16 = 3×7 +9 -14
If you want two expressions, rearrange this to form a different expression. One possibility is ...
16 = 9 + 3×7 -14
