Class 6 | Ch6: Integers
Integers: ...-3,-2,-1,0,1,2,3... Right=greater, left=smaller on number line.
Positive > Zero > Negative. Among negatives: closer to zero is greater (-2>-5).
Addition: same sign(add, keep sign), different signs(subtract smaller absolute, keep sign of larger).
Subtraction: a-b = a+(-b). So 5-8=5+(-8)=-3. Also -3-(-5)=-3+5=2.
Ascending: -8<-5<-1<0<2<3.
Real life: temperature below zero, basement floors, bank withdrawals.
Common mistake: -5 is NOT greater than -2. Subtracting negative = adding positive: 5-(-3)=8.
