rozwiążcie kilka zadan z matmy proosze . temat to odejmowanie liczb calkowitych ...
1. uzupełnij :
8-5=
5-5=
3-5=
0-5=
(-5)-5=
(-45)-5=
2. Oblicz
(-3)-1=
(-3)+(-1)=
B)
2-4=
2+(-4)=
(-8)-7=
(-8)+(-7)=
3.

8-5= = 3
5-5= 0
3-5= -2
0-5= -5
(-5)-5= -10
(-45)-5= -50
2. Oblicz
(-3)-1= -4
(-3)+(-1)= -3-1=-4
B)
2-4=-2
2+(-4)=2-4 = -2
(-8)-7=-15
(-8)+(-7)=-8-7 = -15
3.
.................-10000=-1
x-10000=-1
x=-1+10000
x= 9999
1-................=-1000
1-x = -1000
-x = -1000-1
-x = -1001
x=1001
8-5=3
5-5=0
3-5=-2
0-5=-5
-5-5=-10
-45-5=-50
zad 2
-3-1=-4
-3+(-1)=-4
b)2-4=-2
2+(-4)=-2
-8-7=-15
-8+(-7)=-15
zad 3
9999-10000=-1
1-1001=-1000
Mam nadzieję że pomogłam ;D
