Give the expression

a) 2.34+3.89

First thing you can do is to write as a whole number and as a decimal

2.34 = 2+0.34

3.89 = 3+0.89

2.34+3.89 = 2+0.34+3+0.89

collect the like terms

2.34+3.89 = 2+3+0.34+0.89

2.34+3.89 = 5+1.23

2.34+3.89 = 6.23

b) 3.77+2.22​

3.77 = 3+0.77

2.22 = 2+0.22

3.77+2.22​ = 3+0.77+2+0.22

3.77+2.22​ = 3+2+0.77+0.22

3.77+2.22​ = 5+0.99

3.77+2.22​ = 5.99
