Example: 2351 = 2 x 103+ 3 x 10 3 + 5 x 10 + 1

23 978 = ((50 x 18) + ((22) x 5) x 52) + (((5x5x2) x (32 x 2)) + (23 x 32) + ((24 x 0.25) + 2))

Exercise 3. Do it like excample ( 10 points )

4 x 4 x 4 = 43

3 x 3 x 3 x 3 = 34 or 81.

-5 x (-5) x (-5) x (-5) x (-5) = (-5)5

Answer done in quote :rolleyes:

Rounding ... 1,2,3,4 turn into 0 and nothing else happens ( 51 = 50, 173 = 170)
Rounding ... 5,6,7,8,9 turns into 0 and +1 to next number (55 = 60, 197 = 200)

If number is 49,99 you may not lose the numbers you have rounded. (49,99 = 50,0; 49,9999 = 50,000)

Are you making us make your math homework??? :crazy: :prophet:

Nope. I do not... I will check yur math tests.

Also why should I copy yah... your works may be incorrect.

+ why I ask for no using calc.???

a) -5+(-5)+2+3-(-5) = -5 -

b) -3 + 3 +3 +3 +3 = 9 +

c) 9 + 10 - 9 + 10 = 20 +



Exercise 2. Do it like excample (5 points) 5 points.
Excample: 2351 = 2 x 103+ 3 x 10 3 + 5 x 10 + 1


23 978= 2 x 104 3 x 103 9 x 102 7 x 101 + 8




Exercise 3. Do it like excample ( 10 points ) 5 points
4 x 4 x 4 = 43


3 x 3 x 3 x 3 =34 +

-5 x (-5) x (-5) x (-5) x (-5) = (-5)-5 -


Exercise 4. Rounding to useful number (10 points) 7,5 points

5 = 10

59 = 60. It is not so correct with "."

0,99 = 1 (or 1,0)



27,5 points finally. ( mark is C [3])
