    PEMDAS. Multiplication and division are performed left to right so

    20/5(2 * 2) = 20/5(4) = 4(4) = 16

    20/(5(2 * 2)) = 20/(5(4)) = 20/20 = 1 but this requires another pair of parentheses.

  • 4 years ago

    20 / 5 ( 2 * 2 ) = 20 / 5 * 4 = (20/5) * 4 = 4 * 4 = 16

  • 4 years ago

    20 / 5 (2 * 2) =

    20 / 5 (4) =

    20 / 20 =

    1.

    Well,

    Google is right :

    As is, without brackets :

    20 / 5 ( 2 * 2 ) = 20 / 5 * 4 = (20/5) * 4 = 4 * 4 = 16

    Now, to obtain 1, you would need to add brackets as follows :

    20 / [ 5 ( 2 * 2 ) ] = 20 / [ 5 * 4 ] = 20 / 20 = 1

    okay ?

    hope it' ll help !!

    Google is treating your coefficient 20/5 as a fraction in front of (2*2). The problem is a lack of grouping symbols.

    Try 5/(4*(2*2))

    This is a basic misunderstanding of how you type in division and multiplication.

    1/2(3) = 3/2 NOT 1/6.

    To get 1/6 you need to type 1/((2*(3))

    First do the operation in parentheses.

    20 / 5 * 4

    Now order of operations says go from left to right. So the division is next.

    4 * 4

    And now do the multiplication.

    16

    If you intended that (2*2) to be in the denominator you need more parentheses:

    20/(5*(2*2)) or simply 20/(5*2*2)

  • 4 years ago

    (20/5)(2*2) = 16.

    20/(5*2*2) = 1.

    20/5(2*2) is ambiguous but the most conventional interpretation would give you the 16.

    20 / 5 ( 2 * 2 ) keeps giving me 16

    Because it is taking as:[20 / 5] * ( 2 * 2 ) = 16, keeps giving me 16

    and

    you want, 20 / [5 ( 2 * 2 )] = 20 / 20 = 1.
