90-40=50+0
using 0 more than once….is that allowed in this problem?
nope
80-10=60+10
using 0 more than once….is that allowed in this problem?
You can only use 0 one time.
55-12=43+0
51+32=83-0
21+11=32+0
60-40=10+10
60-10=25+25
9-3=3+3
90-30=30+30
55-12=43+0
52-41=3+8
78-40=23+15
70-50=50+40
19-78=35+24
30+30= 50=10
It is suppose to be 30+30 = 50+10
It is cause it is 30+30=50+10
30-20=1+9
93-13=44+36
19+12=43-12
87-23=49+15
09-01=01+07
45-20=16+9
45-20=9+16
90-80=10+9
50-25=17+8
My answer is 89- 76=13+00
My answer is 89- 76=13+00 this is my answer
99-45=45+45
60 – 10 = 25 + 25
32-10=11+11
98-32=54+10
89-14=63+12
78-54=01+23
96 – 32 = 64
50 + 14 =64
68-36=12+20
35 + 45 = 80 + 10
90-40 = 25+25
9-3 = 5 + 1
60-20=10+30
78-40=23+15
98-32=56+10
89-14=63+12
98-10=63+25
98 – 74 = 23 + 01
98-10=63+25
Hi, I´m a teacher. This website is so cool 🙂
98 – 52=36 +10 (Ivy)
69 – 08 = 24 + 37 (Ali)
97 – 06 = 73 +18 (Mrs Hamer)
80 – 36 = 19 + 25 (Luka)
98 – 16 = 50 + 32 (Aadarsh)
85 – 14 = 69 + 02 (Bayrin)
89 – 13 = 26 + 50 (Ivy)
I agree that, as written, using zero repeatedly is not allowed. However, allowing just zero to be used more than once might be a nice way for some kids to gain access. Then you could remove that allowance as a constraint to push kids’ thinking…
98-15=63+20
98 -65 = 23 + 10
