2. Calculează în două moduri:
(2 + 3) x 5 =
(9 - 4) x 8 =
(4 + 5) x 8 =
(8 - 3) x 7 =
(2 + 1 + 3) x 4 =
(5 + 1 + 2) x 7 =

(2+3) x 5 = 5 x 5 = 25
(2+3) x 5 = (2x5) + (3x5) = 10+15 = 25
(9-4) x 8 = 5 x 8 = 40
(9-4) x 8 = (9x8) - (4x8) = 72 - 32 = 40
(4+5) x 8 = 9 x 8 = 72
(4x8) + (5x8) = 32 + 40 =72
(8-3) x 7 = 5 x 7 = 35
(8x7) - (3x7) = 56 - 21 = 35
(2+1+3) x 4 =6 x 4 = 24
(2x4) + (1x4) + (3x4) = 8+4+12 = 24
(5+1+2) x 7 = (5x7) + (1x7) + (2x7) = 35+7+14 = 56
(5+1+2) x 7 = 8x7 = 56

Explicație pas cu pas:
(2 + 3) × 5 = 5 × 5 = 25
(2 + 3) × 5 = (2 × 5) + (3 × 5) = 10 + 15 = 25
(9 - 4) × 8 = 5 × 8 = 40
(9 - 4) × 8 = (9 × 8) - (4 × 8) = 72 - 32 = 40
(4 + 5) × 8 = 9 × 8 = 72
(4 + 5) × 8 = (4 × 8) + (5 × 8) = 32 + 40 = 72
(8 - 3) × 7 = 5 × 7 = 35
(8 - 3) × 7 = (8 × 7) - (3 × 7) = 56 + 21 = 35
(2 + 1 + 3) × 4 = 6 × 4 = 24
(2 + 1 + 3) × 4 = (2 × 4) + (1 × 4) + (3 × 4) = 8 + 4 + 12 = 24
(5 + 1 + 2) × 7 = 8 × 7 = 56
(5 + 1 + 2) × 7 = (5 × 7) + (1 × 7) + (2 × 7) = 35 + 7 + 14 = 56
