Iekavu atvēršana. Zīmes ienešana iekavās

2
Ja pirms iekavām ir + zīme, tad, iekavas atmetot saskaitāmiem zīmes nemainās. Pirms iekavām + zīme
+ ( a + b ) = a + b
+ ( - a + b ) = - a + b
+ ( a - b ) = a - b
+ ( - a - b ) = - a - b
3
Ja pirms iekavām ir − zīme, iekavas atmetot, iekavās ieslēgtie saskaitāmie maina zīmes uz pretējo.
− ( a + b )= − a − b
− ( a − b ) = − a + b
− ( − a + b ) = a − b
− ( − a − b ) = a + b
