easy one, just test each operation mentally. 2+5=7, 2-5=-3, 2*5=10, 2/5=.4 so (1) gives multiplication. 5+5=10, 5-5=0, 5*5=25, 5/5=1 so (2) gives multiplication too. D.
nice, that's the fastest way. i was overthinking it lol
wait shouldn't the answer be D? both statements independently point to multiplication which is 10.
yeah that's what I got too
same, each statement alone works so it's D
thanks, helpful!
is this really sub-505? felt like a freebie after the last few DS questions i did 😅
lol right, nice to get one that doesn't make me question my life choices
What it tests
Your fluency with the order of operations, fractions, decimals, and basic number sense — the foundation every quant question leans on.
Common trap
Applying the order of operations out of sequence or rounding intermediate values before the final step.
