  • Q9

    Covid - 19 was fast approaching and  Ivan wanted to know the difference between the infected persons and those who recovered from the virus. If there are 1723 infected and 494 who recovered. what will be the correct equation to solve Ivans problem?

    -1723 + 494 =n

    1723 – 494 = n

    494 - 1723 =n
