Zad.1
Chyba o to chodzi:
PIERWSZA TABELKA
10 - 2
1 - 2
-5 - 2
-2 - 2
DRUGA TABELKA
-10 * 6
-10 * -3
-10 * 2,3
-10 * 0,25
______________________________
Zad.2
a) 6*(-4) + 1 = -24
6*0 + 1 = 0 + 1 = 1
6 * -5 + 1 = -30 + 1 = -29
b) 8 - 10 = -2
8 - (-1) = 9
8 - 1/2 = 7 1/2
c) 3 * (7 - 3) = 3*4 = 12
7* (7 - 7) = 7*0 = 0
-2* (7 - (-2)) = -2 * 9 = -18
d) 6 - 3*5 = 6 - 15 = -9
6 - 3 * (-1) = 6 - (-3) = 9
6 - 3*0 = 6 - 0 = 6
______________________________
Zad.3
5x
5*1 = 5
5*0 = 0
5* (-1) = -5
-----------------
2x - 4
2*1 - 4 = 2 - 4 = -2
2*0 - 4 = 0 - 4 = -4
2* (-1) - 4 = -2 - 4 = -6
------------------
x(x - 1)
1*(1 - 1) = 1*0 = 0
0*(0 - 1) = 0* -1 = 0
-1 * ((-1) - 1) = -1 * -2 = 2
------------------
4 - x
4 - 1 = 3
4 - 0 = 4
4 - (-1) = 5
Szczegółowe wyjaśnienie:
Mam nadzieję że pomogłam :)
