Penjelasan dengan langkah-langkah:

[tex]1. \: ( - 67) + 78 = 11[/tex]

[tex]2. \: 79 - ( - 64) = 79 + 64 = 143[/tex]

[tex]3. \: 125 + 456 = 581[/tex]

[tex]4. \: ( - 69) - ( - 31) = - 69 + 31 = - 38[/tex]

[tex]5. \: 98 - ( - 2) =98 + 2 =100[/tex]

[tex]6. \: 56 - ( - 44) =56 + 44 = 100[/tex]

[tex]7. \: 124 - 67 = 57[/tex]

[tex]8. \: 345 - ( - 5) =345 + 5 = 350[/tex]

[tex]9. \: 78 + 90 = 168 [/tex]

[tex] 10. \: ( - 243) + ( - 222) = - 465[/tex]
