Answer 1

A)400+39-9-94

400+39−9−94

=439−9−94

=430−94

→ =336 ←

b)25×100+36-3-8

(25)(100)+36−3−8

=2500+36−3−8

=2536−3−8

=2533−8

→ =2525 ←

c)(4+5)+5+8-(3+4)

4+5+5+8−(3+4)

=9+5+8−(3+4)

=14+8−(3+4)

=22−(3+4)

=22−7

→ =15 ←

d)3+(2+4)-(20×5)(16×5)-18

3+2+4−(20)(5)(16)(5)−18

=3+6−(20)(5)(16)(5)−18

=9−(20)(5)(16)(5)−18

=9−100(16)(5)−18

=9−(100)(80)−18

=9−8000−18

=−7991−18

→ =−8009 ←

e)7+(5+3)+64-(3×4)

7+5+3+64−(3)(4)

=7+8+64−(3)(4)

=15+64−(3)(4)

=79−(3)(4)

=79−12

→ =67 ←
