Answer 1

Answer:

• 250
• 3600
• 4800
• -300
• -320
• 160
• -140
• 0
• 167300
• -1600

Step-by-step explanation:

First of all, you should know the rules of BODMAS

B- bracket

O- Of

D- division

M- multiply

A- addition

S- subtraction

You have to solve these in series, so first solve the bracket, then of,then division,then multiply,then addition and at last subtraction.

• 25×(8+2)

First we will solve the bracket,i.e., (8+2)

25×10=250

Similarly we will solve rest of them

• 72×(36+14)

72×50=3600

• 48×76+48×24

here, to make the calculation easier, we can take 48 common

so, 48(76+24)

48×100=4800

• (-6)×30+(-6)×20

-6(30+20)

-6×50=-300

• 18×(-16)+2×(-16)

-16(18+2)

-16×20= -320

• 20×12+20×(-4)

20(12+(-4))

20×8=160

• 14×10+14×(-20)

14(10+(-20))

14×(-10)= -140

• 76×(-18)+76×18

76(-18+18)

76×0=0

• 1673×99-(-1673)

[-1673 can also be written as -1673×1]

1673×99-(-1673)×1

1673×99+1673×1

1673(99+1)

1673×100

167300

• 40×(-23)+40×(-17)

40(-23-17)

40×-40

-1600
