1)Simplify:
a) 27- [5+ [28-(29-7)}]
b) -25 + 14 = (15-3)
c) (-216) + (-12)
d) (-5) * 7 * (-5) * (-8)
2) What will be the sign of the product if we multiply 40 negative integers and 98 positive
integers?
3) Arrange the numbers in ascending order:
-31, 139, -203, -96,0, 2408

Answer:
1 a. 27-[5+[28-(29-7)}]
= 27-[5+{28-22}]
= 27-[5+6]
= 27-11
=16ans.
b. -25+14= (15-3)
= LHS
-25+14 =1 1
RHS
(15-3) =1 2
LHS doesn't equal to RHS.
c.(-216)+(-12)
=-216+-12
= -228 Ans.
d.(-5)×7×(-5)×(-8)
=-35 × -5 × -8
= 175× -8.
= -1400ans
2. -40× 98
=- 3,920
so when we multiply positive no +ve too negative no -ve our answer is in
negative -ve.
3.Arrange the numbers in ascending order:
3.Arrange the numbers in ascending order:-31, 139, -203, -96,0, 2408
= -203, -96 ,-31,0,139,2408.
To find the greater no among two
integers always see on the right side
because the no which lies in right
is always greater than the no which
lies in left side.
