I am a 4th grader and i need help with these problems.

1. -6f X (7-+4)9>4t<l)

A. 87t
B. Defined Value ****
C. #6
D. None of the above.

2. 58,385 X 957,482,002

A. -8
B. Undefined Integer
C. g7
D. 536,482,995,102,847

#1

(a) unbalanced parentheses
9>4t<l) ??
both f and t a d l?
Fix the typos and try again. Use * for multiplication online. And 7-+4 is probably better just as 7-4 (unless you meant something else)

#2 google makes a good calculator. But even without it, the only numeric answer presented is D. But even it is wrong, since 58*95 = 5510 but D starts with 5364.

More typos? g7?
