(65 - 60) X (2 X 3) = X =
Spacer.gif (42 bytes)
(5 X 2) + (3 X 7) = + =
Spacer.gif (42 bytes)
(7 + 7) - (9 + 3) = - =

(25 - 15) X (1 X 4) = X =
Spacer.gif (42 bytes)
(4 X 3) + (6 X 4) = + =
Spacer.gif (42 bytes)
(10 + 10) - ( 7 + 1) = - =
Spacer.gif (42 bytes)
(48 - 20) X (1 X 1) = X =
Spacer.gif (42 bytes)
(18 - 2) - (5 + 3) = - =
Spacer.gif (42 bytes)
(8 X 2) + (6 X 3) = + =
Spacer.gif (42 bytes)
(48 - 42) X (22 - 20) = X =
Spacer.gif (42 bytes)
(56 - 16) + (5 - 2) = + =

 

Practice subtracting numbers that end in a 9 using mental math.

 

55 - 19 = 55 - 20 = +1 =
spacer.gif (42 bytes)
33 - 9 = 33 - 10 = + 1 =
spacer.gif (42 bytes)
28 - 9 = 29 - 10 = + 1 =
spacer.gif (42 bytes)
67 - 29 = 67 - 30 = + 1 =
spacer.gif (42 bytes)
48 - 19 = 48 - 20 = + 1 =
spacer.gif (42 bytes)
84 - 49 = - = 34 + 1 = 35
spacer.gif (42 bytes)
45 - 19 = - = 25 + 1 = 26
spacer.gif (42 bytes)
52 - 9 = - = 42 + 1 = 43
spacer.gif (42 bytes)
74 - 49 = - = 24 + 1 + 25
spacer.gif (42 bytes)
58 - 9 = - 10 = 48 + 1 = 49

 

Practice subtracting numbers in the hundreds.

 

433 - 196 = 433 - 200 = + 4 =
spacer.gif (42 bytes)
367 - 192 = 367 - 200 = + 8 =
spacer.gif (42 bytes)
244 - 29 = 244 - 30 = + 1=
spacer.gif (42 bytes)
135 - 27 = 135 - 30 = + 3 =
spacer.gif (42 bytes)
320 - 198 = 320 - = + 2 = 122
spacer.gif (42 bytes)
200 - 37 = 200 - 40 = + 3 =
spacer.gif (42 bytes)
169 - 98 = 169 - 100 = + 2 =
spacer.gif (42 bytes)
712 - 193 = 712 - 200 = + 7 = 519
