Arthimetic questions

Have a go at these questions.  Use the most efficient way.  It could be working it out in your head, knowing place value, using column addition,  using column subtraction , using the grid method for multiplication or  knowing that division is the inverse of multiplication.

 B.       352  + 629 =                              H.      2 x 6 x 3 =

C.      682  – 450 =                               I .  2 x    Image result for square   =   4 x 4

D.       43  x   Image result for square  = 0                              J.     2 x  6   =  46 Image result for divided sign png Image result for square

 E.        48 x  5 =                                    K   3+3+3+5+5+5 +2+2+2+2 =

F.     56 Image result for divided sign png  Image result for square = 8                                 L.   200 –   Image result for square  =  5 x 12

  1. A) 2568 – 100 = 2468
    B) 352 + 629=981
    C) 682 – 450 = 232
    D) 43 X 0 = 0
    E) 48 x 5 = 240
    F) 56 divide 448 =8 ( i will be puting the word divide instead of the sign because the sign wasnt on my keyboard)
    G) 34 + 49 – 40 = 9
    H) 2 x 6 x 3 = 36
    I) 2 x 2 = 4 x 4
    J) 2 x 6 = 46 divide 12
    K) 3×3 + 5×3 + 2×4= 29
    L) 200 – 205 = 5 x 12

    • F is not correct. You cannot divide (share ) the smaller 2 digit number by the 3 digit number.
      G is not correct. 34 + 49 = 83 83 -40 = 43 NOT 9
      I is not correct 2 x2 is not the same as 4 x 4
      J is not correct 2 x 6 = 12 46 divide by 12 = 3. 83 12 and 3 are not =
      L is not correct You cannot do 200 (smaller number ) – 205 (biggest number)

  2. 2568 – 100 =2468

    352 +629 =981

    682 – 450 = 232

    43 x 0 = 0

    48 x 5 = 240

    56/7=8

    30+6-40=9

    2x6x3=36

    2×8=4×4

    2×6=46 /12

    3+3+3+5+5+5 +2+2+2+2 =29 =3×3=9 /5×3=15/2×4=8 8 +9+15=29

    200 – 60 = 5 x 12
