sorry,where question?

lgnoring whether the first number is larger or smaller than the second,the number of cobinations is 4 x 3 x 2 x 1 = 24.

half of these will have the first number larger than the second,and half will be the other way around.so there are 12 combinations

to make the total large as possible,the large digits should have place value as large as possible.that is , 9 and 8 will be in the tens positions of the two numbers.

Then 3 and 2 will be in the units positions.

Then the sum is either  93 + 82 = 175 or 92 + 83 = 175,both with total 175

alternative 1

in cents, 500 : 8 = 6r20 so that he buys 6 chocolates and has 20 cents left

alternative 2

multiples of 80,60, 240,320,400,480,560.from this,he can afford 6 chocolates but not 7

the number of wheels is :

4 x 2 + 2 x 3 + 1 x 4 = 18 ( wheels)

                           answer: 18...

make friend me me

a) The term number of the sum s is

( 101 - 1 ) : 3 + 1 = 34 (number)

b) number 50 is

( 50 - 1 ) . 3 + 1 = 148

c) total S is

( 1 + 100 ) . 34 : 2 = 1717

                         answer: a) 34 number

                                       b) 148

                                       c) 1717

30 x 40 = 1200

tcik nha

250 + 250 = 300

tui,hứa lại

A bit ridiculous

this is a 2200

tui nha

river

the largest number is 3 digits is:999

50 + 50 = 100

20 + 20 = 40

24 x 25 = 600

nha, lại

500.000 + 500.000 = 1.000.000
