Question

If a×b is = ab then why not 4×7 = 47 instead of 28???

Answer 1

HLW DEAR

❤❤❤❤❤❤

a × b = ab

Would You Can Tell Me Difference Between Both???

a × b IS ALSO PRODUCT OF TWO NUMBER

&

ab IS ALSO PRODUCT OF TWO NUMBER.

IN SIMPLIFICATION IF TWO VARIABLE HAS BEEN WRITTEN TOGETHER AND THERE IS NO SIGN THEN WE SHOULD KNEW THAT.

BETWEEN THEM THERE IS MULTIPLICATION SIGN [ × ]

SO THATS WHY

a × b = ab

and

4 × 7 = 47

Answer 2

lol

ab means a×b symbolises a is in multiplication with b .
Since they are in like terms therefore they can't be subtracted,added,multiplied,squared with each other .
Therefore we write
a×b is = ab

And since 4 and 7 are like terms . So they can be added , subtracted , multiplied , divided with each other.
Therefore we write 4×7 = 28 instead of writing 47.

Keep your such silly question in your mind.
don't ask them otherwise everyone will say you mad.

And
Good luck for your final exams.
