Cool!
“Barbara has 695 marbles. She gives her sister 283 marbles. She now has 412 marbles left.” The answer doesn’t work because you can only use each number once and you’ve used “2” twice.
I’m not understanding how you got the answer.
That’s true
Barbara has 603, gave her sister 125, left with 478.
Barbara has 890 marbles. She gives her sister 154 marbles. She now has 736 marbles left.
907-586=321 (Davin)
927-541=386 (Sara)
941-235=706 (Joshua)
951-703=248 (Triton)
357-148=209 (Kayden)
918-273=645 (Ryland)
639-157=482 (Cameron)
603-125=478
729-543=186
576 – 194 = 382
896-654=242
625-278=347
910 – 342 = 568
532 – 345 = 187
678-234=444
please, I need help, with the same question, except you can only use the same numbers ONCE!
My third grader, Hayden, figured out 951-243=708
928-374=554
930-125=805
Barbara has 1567 marbles. She gives her sister 432 marbles. She now has 1135 marbles left.
