1. Name Date ___________
Add integers with same sign.
(-8) + (-9) + (-56) =
Above given problem is a simple expression to add three integers but they have
negative sign inside the bracket. Numbers with same sign are on same side of the
mid point of the number line (Zero).
To add negative numbers, we add those numbers, as one would usually do. Then
we put a negative sign on the result obtained.
Adding these numbers and solving the expression, we get the result as -73
Answer: -73

Write an addition sentence.
Here we have to express the above figures as an addition sentence.
Here the circle with one horizontal line represents to -1 i.e. one unit of negative
number and the circle with two lines - one horizontal line and another vertical
represents +1 i.e. one unit of positive number.
Count the number of negative units =2
Count the number of positive units =3
Write the addition sentence

Name Date
Add integers with same sign.
1 9 + 6 + 45 = 2 ( -59) + (-32) =
3 (-42) + (-25) = 4 (-71) + (-14) =
5 (-9) + (-28) + (-18) = 6 3 + 56 + 18 =
7 18 + 32 = 8 (-653) + (-40) + (-92) =
9 (-986) + (-182) + (-306) = 10 84 + 95 =

Find what is missing from the equations.
1 (-56) + = (-89) 2 29 + = (-37)
3 (-18) + = 53 4 (-86) + = (-99)
5 (-13) + = (-24) 6 15 + = (-36)
7 (-41) + = 82 8 (-16) + = (-29)
9 (-19) + = (-38) 10 (-53) + = 68
