7*9 = 9*(10 - 3)
= 90 - 27
= 63
you would go: (30x9) + (7x9) = 270 + 63 = 333 which is the same as if you typed 37x9 into the calculator and got 333!

trial and error; 5x7=35 9x9=82, difference of 47. not big enough difference. 7x9=63 11x11=121. differenence of 58, which is too big. sorry, but this means there is not answer.
Expressions within parenthases (brackets) should be done first. Then each operation should be done in turn from left to right. Therefore 4+7x(5+4) would be 4+7x9 and then 11x9 =99.
you would go: (30x9) + (7x9) = 270 + 63 = 333 which is the same as if you typed 37x9 into the calculator and got 333!
Using repeated addition to find the product of 7x9 can be inefficient, as it involves adding the number 7 a total of 9 times (or vice versa). This results in a lengthy process that can be cumbersome for larger numbers. Instead, multiplication is a more efficient operation that provides the answer directly, as it represents a faster way to combine equal groups. For 7x9, the product is 63, which can be calculated more swiftly than through repeated addition.
welll first of all 9x7=63 and 7x9=63

9x7 and 7x9 are the same and equals to 63 whereas 8x8 equals to 64 so therefore 8x8 is greater than both 9x7 and 7x9.

7+9=16 7x9=63 63-16 = 47

no if you multiply two primes for example 7x9=63 63 is not prime because 9 and 7 go into it
