# Subtracting Integers

Subtracting integers is the second operations on integers, among the four fundamental operations on integers.

Change the sign of the integer to be subtracted and then add.

(i) Subtract: +3 from +9

(+9) – (+3)

Here the +3 is subtracted from +9

= +9 – 3, [(+ 3) changes to (-3)]

Now add +9 and -3 using the addition of integers rule.

= +6

(ii) Subtract: -7 from +12

(+12) - (-7)

Here the -7 is subtracted from +12

= +12 + 7, [(-7) changes to (+7)]

Now add +12 and +7 using the addition of integers rule.

= +19

(iii) Subtract: +8 from -18

(-18) – (+8)

Here the +8 is subtracted from -18

= -18 - 8, [(+ 8) changes to (-8)]

Now add -18 and -8 using the addition of integers rule.

= -26

(iv) Subtract: -4 from -11

(-11) – (-4)

Here the -4 is subtracted from -11

= -11 + 4, [(-4) changes to (+4)]

Now add -11 and +4 using the addition of integers rule.

= -7

(v) Subtract: +44 from +99

(+99) – (+44)

Here the +44 is subtracted from +99

= +99 – 44, [(+ 44) changes to (-44)]

Now add +99 and -44 using the addition of integers rule.

= +55

(vi) Subtract: -63 from +87

(+87) - (-63)

Here the -63 is subtracted from +87

= +87 + 63, [(-63) changes to (+63)]

Now add +87 and +63 using the addition of integers rule.

= +150

(vii) Subtract: +41 from -76

(-76) – (+41)

Here the +41 is subtracted from -76

= -76 - 41, [(+ 41) changes to (-41)]

Now add -76 and -41 using the addition of integers rule.

= -117

(viii) Subtract: -16 from -46

(-46) – (-16)

Here the -16 is subtracted from -46

= -46 + 16, [(-16) changes to (+16)]

Now add -46 and +16 using the addition of integers rule.

= -30
