Question

a) Solve the following : (any 5)

1) Add: 2 + 6 + 8 ; 16 + 13 + 18
2) Subtract : (4 + 16) ; (19 − 14 + 16) 3) 3)Multiply: (−3 ²) × (−4)
4) 5 − 4 = 1
5) (4 + 5) × (9 + 7)
6) In the algebraic expression 4 ² − 2 + 5 : find the term , coefficient and variable
7) (11 − 12 + 3) − (9 + 7 − 8)​

Answer 1

Answer:

1. 2+6+8=16 ; 16+13+18=47

2. (4+16)=20 ; (19-14+16)=21

3. (-3)²×(-4)=(9)×(-4)= -36

4. (5-4=1) = (5=1+4) = (5=5)

5. (4+5)×(9+7)=9×16=144

6. I don't know

7. (11-12+3)-(9+7-8)=(2)-(8)= -6
