The answer would be an overestimate.
when both factors in a multiplication problem are rounded up to estimate the product, the estimate is an overestimate.
You would call that an estimate, or overestimate.
If you rounded up, it's an overestimate, if you rounded down, it's an underestimate. If you did both, whatever you did more of will prevail.

overestimate
Assuming that the estimate is based on sensible approximations, there is no simple way. You will need to compare the estimate and the true value. If you've rounded up, the estimate will be greater. If you've rounded down, the estimate will be less.
Overestimation, perhaps.
It's not actually a product. "Product" is the result of multiplication only.(20)20 = 104,857,600,000,000,000,000,000,000 (exact; not rounded)
If you have rounded up, it will be an overestimate. If you have rounded down, it will be an underestimate.
If you rounded up, it's an overestimate, if you rounded down, it's an underestimate. If you did both, whatever you did more of will prevail.
765 can be rounded to 800, and 433 to 400. 800 x 400 = 320,000
