$34 + \underset{10∧6}{16} = 34 + 10 + 6 = 44 + 6 = 50$
$\underset{10∧9}{19} + 51 = 51 + 10 + 9 = 61 + 9 = 70$
$60 - \underset{40∧9}{49} = 60 - 40 - 9 = 20 - 9 = 11$
$80 - \underset{30∧9}{35} = 80 - 30 - 5 = 50 - 5 = 45$
$48 + \underset{40∧2}{42} = 48 + 40 + 2 = 88 + 2 = 90$
$40 - \underset{10∧7}{17} = 40 - 10 - 7 = 30 - 7 = 23$
$30 - \underset{10∧2}{12} = 30 - 10 - 2 = 20 - 2 = 18$
$36 + \underset{20∧4}{24} = 36 + 20 + 4 = 56 + 4 = 60$
