19.334g + 0.14g =
362.9g – 56g =
0.0297mL + 0.864mL =
23.65 x 9.1331 =
Subtract:
a. 200km – 24.9km =
b. 13.9g – 0.003g =
c. 31.64m – 14.9m =
Multiply:
a. 33.2 x 9.6 =
b. 100mm x 2.54mm =
c. 0.00009g x 538g =
Divide:
a. 6008cm² / 2.365cm =
b. 72cm³ / 7cm =
c. 600 / 38 =

9.301cm + 9.6cm + 0.37cm + 17.6cm =
9.4km + 1.73m + 1200cm =
5.365g – 9.3g =
16.3156m – 9.0m =
19.00 + 33.001 =
131cm x 9.4cm =
8.3654m x 9.370m =
37.3 / 9.11s =
99.003g / 14.000009ml =
