Answer:
1. +14 - (+9)
= 14 - 9
= 5
2. - 5 - (-10)
= -5 + 10
3. +19 - (-6)
= 19 + 6
= 25
4. -7 - (+16)
= -7 - 16
= -23
5. -45
note:
1. pag same sign pagadd mo sila then copy the sign
2. pag different sign pagminusin mo sila then copy the sign nung higher number
PRODUCT
1. (-12)(-3) ( negative times negative equals
positive)
= 36
2. 45
3. 0 ( Any no. multiply by zero equals zero)
4. 81
5. 21 ( negative times postive equals negative)
Quotient
1. 2
2. -5
