I variant


  1. Koordinata nurida qo‘shishni tasvirlang: 4 + 3.

  2. Qo‘shishning guruhlash qonunini qo‘llab amallarni bajaring:

(54 271 + 39 999) + 10 001.

  1. Qulay usul bilan hisoblng: (6112 + 1596) – 496.

  2. Ifodani yozing: а) 19 + 5 va 18 – 3 yig‘indisini; b) х + 8 va b – 9 ayirmasini.

  3. Agar n = 73 bo‘lsa, (135 + n) – 23 ifodaning qiymatini toping.



II variant

  1. Koordinata nurida qo‘shishni tasvirlang: 4 + 5.

  2. Qo‘shishning guruhlash qonunini qo‘llab amallarni bajaring:

19 999 + (4801 + 15 200).

  1. Qulay usul bilan hisoblng: (8593 + 1407) – 999.

  2. Ifodani yozing: а) 28 + 7 va 15 – 4 yig‘indisini; b) х + 10 va b – 8 ayirmasini.

  3. Agar n = 65 bo‘lsa, (135 + n) – 23 ifodaning qiymatini toping.
