4.4 + 7 = 117 + 4 = 1111 − 4 = 711 − 7 = 4
5.9 + 5 = 145 + 9 = 1414 − 9 = 514 − 5 = 9
6.8 + 10 = 1810 + 8 = 1818 − 8 = 1018 − 10 = 8
7.6 + 9 = 159 + 6 = 1515 − 6 = 915 − 9 = 6
8.5 + 10 = 1510 + 5 = 1515 − 5 = 1015 − 10 = 5
9.9 + 2 = 112 + 9 = 1111 − 9 = 211 − 2 = 9
10.7 + 10 = 1710 + 7 = 1717 − 7 = 1017 − 10 = 7
11.4 + 8 = 128 + 4 = 1212 − 4 = 812 − 8 = 4
