    let say you have a formula
    10101 x (X)
    note:jibu linatakiwa liwe 6 figure
    ambapo namba mbili zitakua zinajirudiarudia swali ni je formula hii ni sahihi if X ni single digit?(reasoning considered)

    Haiwezi kuwa sahihi kwa single digit because the multiplier(10101) it contains 0 and 1 and it has 5 digits so the answer will have 5 digits and not 6 digits so the formula it's not applicable for 0<X<10(while X is an integer)

    Siyo sahihi. 1x(X) =X, 0x(X) =0 for any value of X. Single digit implies 0<X<10 where X is a whole number. Therefore 10101x(X)=X0X0X which is a 5 figure number.

    Let x =1=01

    hence 10101x1=10101x01

    multiply using long method ie

    10101
    ,,.. x01
    ------------
    00000
    .. 10101 add
    -----------
    010101 as required.
    -------------

    It is possible if hiyo number kubwa inayozidishiwa na single digit nayo inajirudia rudia,
    Say 202020 x 3 = 606060

    Hiyo No ya kwenye formula ni 10101 ina 5 digits and specifically it contains only 0 and 1 sasa uniambie izidishwe na single digit Number how comes the answer to have six digits.

    Yes, this is possible for any interger X:0<X<10 when the result obtained is been rounded off to 6 significant figures. For example,10101x9~909090(corect to 6 s.f) where 0 and 9 are the reccuring digits.
    Conlusion:10101x(X) can be rounded off to 6 s.f when multiplied by any interger X:0<X<10 and zero been placed after the last digit of the product obtained.
