10-05: input two number and display the result

Question

Write a program that let the user input two number and displays the result as the example below:

輸入兩個數字，做加減乘除的運算

Example input 1:

5 6

Example output 1:

5+6=11
5-6=-1
5*6=30
5/6=0.833333

Example input 2:

1.23 3.45

Example output 2:

1.23+3.45=4.68
1.23-3.45=-2.22
1.23*3.45=4.2435
1.23/3.45=0.356522

Remember: Your output maybe 100% correct, but your code matters!
