int main()
{
	int A, B, soma, sub, mult;
    scanf("%d %d", &A, &B);
    soma = A + B;
    sub = A - B;
    mult = A * B;
    if(soma > sub && soma > mult){
        printf("%d\n", soma);
        printf("%d + %d = %d%d - %d = %d%d * %d = %d%d\n", A, B, soma, A, B, sub, A, B, mult, soma);
    }
    else if(sub > soma && sub > mult){
        printf("%d\n", sub);
        printf("%d + %d = %d%d - %d = %d%d * %d = %d%d\n", A, B, soma, A, B, sub, A, B, mult, sub);

    }
    else{
        printf("%d\n", mult);
        printf("%d + %d = %d%d - %d = %d%d * %d = %d%d\n", A, B, soma, A, B, sub, A, B, mult, mult);

    }
