Answer 1

2) 2000 cm + 15 cm + 12 cm = 2027 cm
3) 11.66 x 6.56 = 76.4896
4) 4.25 - 0.7828 = 3.4672
5) 6.73 - 0.8 x 1.98 = 6.73 - 1.584 = 5.146
6) 75.69 - 10.89 = 64.8
7) 0.75^2 + 0.12^2 = 0.5625 + 0.0144 = 0.5769
8) 0.64 - 0.49 + 0.36 - 0.25 = 0.26
9) 3/8 x 2/5 x 60/1 = 360/40 = 9/1
10) 0.1806 + 1.8194 = 2
11) 13.9 - 10.3 = 3.6
      19.72 + 3.6 =23.32
12) a + a x 1.2 = 11.3344
      2.2a = 11.3344
      a = 11.3344 : 2.2
      a = 5.152
      a x 1.2 = 5.152 x 1.2
      a x 1.2 = 6.1825
